The mountain is notorious for its erratic weather. On the afternoon of April 12, 1934, the Mount Washington Observatory recorded a windspeed of 231 miles per hour (372 km/h) at the summit, the world record from 1934 until 1996. Mount Washington still holds the record for highest measured wind speed not associated with a tornado or tropical cyclone.[4][a]

The mountain is located in the Presidential Range of the White Mountains, in Coös County, New Hampshire. The mountain is in several unincorporated townships, with the summit in the township of Sargent's Purchase. While nearly the whole mountain is in the White Mountain National Forest, an area of 60.3 acres (24.4 ha) surrounding and including the summit is occupied by Mount Washington State Park.

The Mount Washington Cog Railway ascends the western slope of the mountain, and the Mount Washington Auto Road climbs to the summit from the east. The mountain is visited by hikers, and the Appalachian Trail crosses the summit. Other common activities include glider flying, backcountry skiing, and annual cycle and running races such as the Auto Road Bicycle Hillclimb and Road Race.

History

Before European settlers arrived in the region, the mountain was known by various indigenous peoples as Kodaak Wadjo ("the top is so hidden" or "summit of the highest mountain") or Agiochook or Agiocochook ("the place of the Great Spirit" or "the place of the Concealed One").[6] The Algonquians called the summit Waumbik, "white rocks".[6][7] The Abenaki people inhabiting the region at the time of European contact believed that the tops of mountains were the dwelling place of the gods, and so among other reasons did not climb them out of religious deference to their sanctity.[8]

The first European to mention the mountain was Giovanni da Verrazzano. Viewing it from the Atlantic Ocean in 1524, he described what he saw as "high interior mountains".[9]Darby Field claimed to have made the first ascent of Mount Washington in 1642.[10] Field climbed the mountain in June of that year to demonstrate to the Abenaki chief Passaconaway that the Europeans bargaining for tribal land were not subject to the gods believed to inhabit the summit, a primarily political move that facilitated colonists' northern expansion.[8] Field again summited Agiocochook in October 1642 on an early surveying expedition that created maps of land as far as Maine, which allowed people from the Massachusetts colony to identify arable coastal areas.[8]

A geology party, headed by Manasseh Cutler, named the mountain in 1784.[11] The Crawford Path, the oldest continuously maintained hiking path in the United States,[12] was laid out in 1819 from Crawford Notch to the summit and has been in use ever since. Ethan Allen Crawford built a house on the summit in 1821, which lasted until a storm in 1826.[11]

 
The second Summit House in 1904

Little occurred on the summit itself until the mid-19th century, when it was developed into one of the first tourist destinations in the nation, with construction of more bridle paths and two hotels. The Summit House opened in 1852, a 64-foot-long (20 m) stone hotel anchored by four heavy chains over its roof. In 1853, the Tip-Top House was erected to compete. Rebuilt of wood with 91 rooms in 1872–1873, the Summit House burned in 1908, then was replaced in granite in 1915.[11] The Tip-Top House alone survived the fire; today it is a state historic site, recently renovated for exhibits. Other Victorian era tourist attractions include a coach road (1861)—now the Mount Washington Auto Road—and the Mount Washington Cog Railway (1869), both of which are still in operation.[13]

For forty years, an intermittent daily newspaper, called Among the Clouds, was published by Henry M. Burt at the summit each summer, until 1917.[14][15]

In 2011 and 2012, Orlando, Florida–based CNL Financial Group, which at the time operated the Mount Washington Hotel at the foot of the mountain, trademarked the "Mount Washington" name when used with a resort or hotel. CNL officials said they were directing their efforts only against hotels and not the numerous businesses in the area that use the name.[16] CNL's application at the U.S. Patent and Trademark Office seeks registration of the trademark "Mount Washington" for any retail service, any restaurant service, and any entertainment service.[17]

The summit station of Mount Washington has an alpine climate or tundra climate (Köppen ET), although it receives an extremely high amount of precipitation, atypical for most regions with such cold weather. However, elevations just beneath treeline have a subarctic climate (Köppen Dfc) which eventually transitions to a humid continental climate (Koppen Dfb) near the mountain's base and the surrounding lower elevations.[19]

The weather of Mount Washington is notoriously erratic. This is partly due to the convergence of several storm tracks, mainly from the Atlantic to the south, the Gulf region and the Pacific Northwest. The vertical rise of the Presidential Range, combined with its north–south orientation, makes it a significant barrier to westerly winds. Low-pressure areas are more favorable to develop along the coastline in the winter due to the relative temperature differences between the northeastern United States and the Atlantic Ocean. With these factors combined, hurricane-force wind gusts are observed from the summit of the mountain on average of 110 days per year. These extreme winds also contribute to the mountain's very short treeline, with elevations as low as 4,400 feet being too hostile to support any plant life more than a few inches in height.[20][21]

Mount Washington once held the world record and still holds the Northern Hemisphere and Western Hemisphere record for directly measured surface wind speed, at 231 mph (372 km/h), recorded on the afternoon of April 12, 1934. A new wind speed record was discovered in 2009: on April 10, 1996, Tropical Cyclone Olivia had created a wind gust of 408 km/h (254 mph) at Barrow Island off the coast of western Australia.[22] (Satellite and radar measurements, e.g. of tornadoes, hurricanes, and air currents in the upper atmosphere, do not officially compete with records for surface measurements.)

The first regular meteorological observations on Mount Washington were conducted by the U.S. Signal Service, a precursor of the National Weather Service, from 1870 to 1892. The Mount Washington station was the first of its kind in the world, setting an example followed in many other countries. For many years, the record low temperature was thought to be −47 °F (−44 °C) occurring on January 29, 1934, but upon the first in-depth examination of the data from the 19th century at NOAA's National Climatic Data Center in Asheville, North Carolina, a new record low was discovered. Mount Washington's official record low of −50 °F (−46 °C) was recorded on January 22, 1885. The official record cold daily maximum is −28 °F (−33 °C) on February 6, 1995.[18] Highs of 0 °F (−18 °C) or below occur on 13 days annually, while lows at or below 0 °F can be expected from November 17 through April 1; from December to March, temperatures rise above freezing on only 15 days.[18]

On January 16, 2004, the summit weather observation registered a temperature of −43.6 °F (−42.0 °C) and sustained winds of 87.5 mph (140.8 km/h), resulting in a wind chill value of −102.59 °F (−74.77 °C) at the mountain.[23] During a 71-hour period from approximately 3 p.m. on January 13 to 2 p.m. on January 16, 2004, the wind chill on the summit never went above −50 °F (−46 °C).[23] The official record high temperature at the summit is 72 °F (22 °C) on June 26, 2003, and August 2, 1975,[24] while the official record warm daily minimum is 60 °F (16 °C) on the latter date.[18] Readings of 60 °F or more at the summit are seen on an average 13.5 days annually.[25]

The primary summit building was designed to withstand 300 mph (480 km/h) winds; other structures are chained to the mountain.[26] In addition to a number of broadcast towers, the mountain is the site of a non-profit scientific observatory reporting the weather as well as other aspects of the subarctic climate of the mountain. The extreme environment creates strong winds and ice at the top of Mount Washington making the use of unmanned equipment problematic. The observatory also conducts research, primarily the testing of new weather measurement devices. The Sherman Adams summit building, which houses the observatory, is closed to the public during the winter[27] and hikers are not allowed inside the building except for pre-arranged guided tours.[28]

The Mount Washington Observatory was built on the summit in 1932 through a group interested in and noting the worth of a research facility at that demanding location.[29] The observatory's weather data have accumulated a climate record since. Temperature and humidity readings have been collected using a sling psychrometer, a simple device containing two mercury thermometers. Where most unstaffed weather stations have undergone technology upgrades, consistent use of the sling psychrometer has helped provide scientific precision to the Mount Washington climate record.[30]

The observatory makes prominent use of the slogan "Home of the World's Worst Weather," a claim that originated with a 1940 article in Appalachia magazine by Charles Brooks, the man generally given the majority of credit for creating the Mount Washington Observatory. The article was titled "The Worst Weather in the World" even though it concluded that Mount Washington most likely did not have the world's worst weather.[28][31]

Precipitation

Due in part to its high prominence, to its situation at the confluence of two major storm tracks, and to the north–south orientation of the Presidential Range ridgeline, which it crowns, Mount Washington receives high levels of precipitation, averaging an equivalent of 91.2 in (2,320 mm) of rain per year,[b] with a record high for a calendar year of 130.14 in (3,305.6 mm) in 1969[32] and a low of 71.34 in (1,812.0 mm) in 1979. Monthly precipitation has ranged from 0.75 in (19.1 mm) in October 1947 to 28.70 in (729.0 mm) in October 2005.[24] Large amounts of precipitation often fall in a short period of time: in October 1996, a record 11.07 in (281.2 mm) of precipitation fell during a single 24-hour period. A substantial amount of this falls as snow, with a seasonal[c] average of around 280 inches (7.1 m) of snow; seasonal accumulation has ranged from 75.8 in (1.93 m) in 1947–48 to 566.4 in (14.39 m) in 1968–69.[18] The record amount of snowfall in a 24-hour period, 49.3 in (125.2 cm), occurred in February 1969, which is also the snowiest month on record with 172.8 in (4.39 m).[24]

Geographical features

Although the western slope that the Cog Railway ascends is straightforward from base to summit, the mountain's other sides are more complex. On the north side, Great Gulf—the mountain's largest glacial cirque—forms an amphitheater surrounded by the Northern Presidentials: Mounts Clay, Jefferson, Adams and Madison.[15] These connected peaks reach well into the treeless alpine zone. Massive Chandler Ridge extends northeast from the summit of Washington to form the amphitheater's southern wall and the incline is ascended by the Mount Washington Auto Road.[15]

 
First aid cache

East of the summit, a plateau known as the Alpine Gardens extends south from Chandler Ridge at about 5,200 feet (1,600 m) elevation. It is notable for plant species either endemic to alpine meadows in the White Mountains or outliers of larger populations in arctic regions far to the north.[35] Alpine Gardens drops off precipitously into two prominent glacial cirques. Craggy Huntington Ravine offers rock and ice climbing in an alpine setting. More rounded Tuckerman Ravine is New England's premier venue for spring back-country skiing as late as June and then a scenic hiking route.[36]

South of the summit lies a second and larger alpine plateau, Bigelow Lawn,[37] at 5,000 feet (1,500 m) to 5,500 feet (1,700 m) elevation. Satellite summit Boott Spur and then the Montalban Ridge including Mount Isolation and Mount Davis extend south from it, while the higher Southern Presidentials—Mounts Monroe, Franklin, Eisenhower, Pierce, Jackson and Webster—extend southwest to Crawford Notch. Oakes Gulf separates the two high ridges.

Uses

The mountain is part of a popular hiking area, with the Appalachian Trail crossing the summit and one of the Appalachian Mountain Club's eight mountain huts, the Lakes of the Clouds Hut, located on one of the mountain's shoulders. Winter recreation includes Tuckerman Ravine, famous for its Memorial Day skiing and its 50-degree slopes. The ravine is notorious for its avalanches, of which about 100 are recorded every year, and which have killed six people since 1849. Scores of hikers have died on the mountain[38] in all seasons, due to harsh and rapidly changing conditions, inadequate equipment, and failure to plan for the wide variety of conditions that can occur above tree line.[39]

The weather at Mount Washington has made it a site for glider flying. In 2005, it was recognized as the 14th National Landmark of Soaring.[40]

Hiking

The most common hiking trail approach to the summit is via the 4.1-mile (6.6 km) Tuckerman Ravine Trail. It starts at the Pinkham Notch camp area and gains 4,280 feet (1,300 m), leading straight up the bowl of Tuckerman Ravine[41] via a series of steep rock steps that afford views of the ravine and across the notch to Wildcat Mountain. Fatalities have occurred on the trail, both from ski accidents and hypothermia. Water bottles may be refilled at the base of the bowl 2.1 miles (3.4 km) up the trail at a well pump near the Hermit Lake Shelters, which offers snacks, toilets and shelter.[42] At the summit is a center with a museum, gift shop, observation area, cafeteria, and the Mount Washington Observatory. Other routes up the eastern slopes of the mountain include the Lion Head, Boott Spur, Huntington Ravine and Nelson Crag trails, as well as the Great Gulf Trail ascending from the northeast. Routes from the western slopes include the Ammonoosuc Ravine and Jewell trails and the Crawford Path and Gulfside Trail (coincident with the Appalachian Trail from the southwest and from the north, respectively).[43]

There are many differences between climbing Mount Washington in summer and climbing it in winter. There are no public facilities on the summit in winter.[44] In the winter months, the most common route is the Lion Head Winter Route, which begins on the Tuckerman Ravine Trail but then turns north to ascend up to Lion Head at elevation 5,033 feet (1,534 m). The winter route variation is recommended to help climbers avoid avalanche danger.[45] Exactly where the route turns from the Tuckerman Ravine Trail depends on the snow conditions. If the amount of snowfall has not been significant, the Lion Head Summer Route may be open. After hiking 2.3 miles (3.7 km) from the visitor center in Pinkham Notch, the trail will take a right turn onto the Lion Head Summer Route. If there has been enough snow accumulation on the summer Lion Head Trail, the Forest Service will open the Lion Head Winter Route, which turns off after approximately 1.7 miles (2.7 km).[45]

Cog railway

Since 1869, the Mount Washington Cog Railway has provided tourists with a train journey to the summit of Mount Washington.[46] It uses a Marsh rack system and was the first successful rack railway in the US.[47]

Races

Every June, the mountain is the site of the Mount Washington Road Race, an event that attracts hundreds of runners. In August the Mount Washington Auto Road Bicycle Hillclimb, a bicycle race, takes place along the same route as the road race.[48] The hillclimb's notable contestants include former Tour de France contender Tyler Hamilton.[49]

On August 7, 1932, Raymond E. Welch became the first one-legged man to climb Mount Washington.[50] An official race was held and open only to one-legged people. Mr. Welch climbed the "Jacob's Ladder" route and descended via the carriage road. At the time of his climb, he was the station agent for the Boston & Maine Railroad in Northumberland, New Hampshire.[50]

The mountain is also the host to one of the oldest car races in the country, the Mount Washington Hillclimb Auto Race, which has been held on and off since 1904. Travis Pastrana set record ascents in 2010, 2014, 2017, and 2021, driving a Subaru WRX STi to a record of five minutes and 28.67 seconds.[51][52][53] In 2014 EVSR created by Entropy Racing was the first electric car to compete at Mt. Washington with an official time for driver Tim O'Neil of seven minutes and 28.92 seconds.[54]

Transmission facilities

 
FM broadcasting station WMTW's ice-covered Mount Washington transmitter site in 1944.[55]

Due to its status as the highest elevation in the northeast United States, the top of the mountain is a popular site for stations that require transmission ranges over a broad territory, but which operate on frequencies that are generally limited to line-of-sight coverage. In 2003, it was reported that the summit was the site used "for three commercial radio stations and dozens of state, federal and private agencies, including the state police".[56]

Use of the mountain summit as a transmitter site dates to the 1930s. At this time investigations were begun into establishing radio stations broadcasting on "Very High Frequency" (VHF) assignments above 30 MHz. Reception of stations operating on these frequencies tended to be limited to line-of-sight distances, so operating from the top of Mount Washington was ideal for providing maximum coverage. As of 1938 it was reported that at least five experimental stations were located on the mountain.[57]

The most prominent of the early experimental stations was W1XER, originally an "Apex" radio station licensed to the Yankee Network, that was moved from Boston to the mountain in 1937, and initially used to relay meteorological information from the weather observatory. With the aid of Edwin H. Armstrong, the station was converted from an AM transmitter into an FM broadcasting station, although the conversion process turned out to be an arduous undertaking,[58] and W1XER did not start broadcast programming on a regular schedule until December 19, 1940.[59] This station's facilities included construction of the original broadcast tower, the Yankee Building housing the crew and transmitter equipment, and the first power house building. Commercial broadcasting commenced on April 5, 1941,[60] initially with the call sign W39B.[61] Effective November 1, 1943 the station call sign was changed to WMTW,[62] and in late 1946 the call letters were changed again, to WMNE. WMNE ceased operations in late 1948, due to excessive maintenance costs, and concern that a mandatory frequency change to the new FM "high band" would cause an unacceptable decrease in transmission range.[63]

In 1954 WMTW, channel 8, licensed to Poland Spring, Maine, constructed a TV tower and transmitter and began operations from the mountain, including local forecasts by (now retired) WMTW transmitter engineer Marty Engstrom.[64] This station relocated its transmitter away from the mountain in 2002, due to concerns that a mandated switch from analog to digital transmissions would result in insufficient coverage if the transmitter remained at the mountaintop.[65]

There are currently two FM stations located at the mountain. 1958 saw the construction of WMTW-FM 94.9 MHz (now WHOM). A second station, WMOU (now WPKQ), moved to the summit in 1987, installing transmitters in the Yankee building and constructing a new broadcast tower behind the building, which is the tallest structure on the summit.

WHOM and WMTW-TV shared a transmitter building, which also housed the generators used to supply electrical power to the various facilities atop the mountain. However, on February 9, 2003, a major fire broke out in the generator room of the transmitter building, which had become the property of the state only a year earlier when WMTW left the summit. The fire destroyed the building, including WHOM's transmitters as well as the summit's main generators, and also spread to the adjacent Old Yankee Power House building, which housed the emergency generator, destroying that building also and disrupting all power to the summit. Temporary generators had to be transported up the mountain to restore power to the observatory and to the Yankee building, which houses important public safety communications equipment. A makeshift generator room was constructed underneath the canopy of the Sherman Adams building across from the public entrance to replace the destroyed buildings. The makeshift generator room was later made permanent when power cables were installed in 2009, delivering grid power to the summit for the first time.

The original Armstrong tower still stands today. The Yankee Building also remains and continues to serve as a communications facility, housing equipment for numerous tenants including cellular telephone providers and public safety agencies. The old sign from the destroyed Old Yankee Power House building was placed above the doorway to the new generator room. WHOM subsequently built a new transmitter building on the site of the old power building, and also installed a new standby antenna on the Armstrong tower. (For the first time since 1948, the Armstrong tower was used for broadcasts.)[66]

The National Weather Service (NWS) forecast office in Gray, Maine, operates NOAA Weather Radio station KZZ41 on 162.5 MHz from the summit of Mount Washington. The NWS coverage map indicates that it can be heard throughout most of New Hampshire, western Maine, northeast Vermont, and portions of southern Canada. During very clear conditions, KZZ41 has the potential to reach the majority of northern Massachusetts (including some northern areas of Greater Boston and much of the North Shore) as well as the majority of Vermont and Maine.[67]

In June 2008, the possibility of television returning to Mount Washington arose, with the filing by New Hampshire Public Television to move WLED-TV from its current location near Littleton to the old WMTW mast on top.[68][69]

Deaths

As of 2019, more than 161 people had died in the Presidential range, since record-keeping began in 1849.[70] Author Nicholas Howe has detailed many of the fatalities on this mountain in his book Not Without Peril published in 2000 and updated in 2009.[71] The foreword to the 2009 edition states that many of the deaths over the past 150 years can be attributed to poor planning and lack of understanding of "the difference in weather between Boston and the mountains. The latter are farther north, farther inland and much higher than the city." William Buckingham Curtis, often posthumously called "the father of American amateur athletics", died from exhaustion on June 30, 1900, near Lakes of the Clouds Hut during a snowstorm.[72]

Artistic tributes

Mount Washington has been the subject of several famous paintings, part of a New England school of art known as White Mountain art.[73] Inspired by the Hudson River School of landscape painting, a number of artists during the Victorian era ventured into the White Mountains in search of natural subjects.[74] Train service in the area spurred increased tourism and the construction of the Glen House where Albert Bierstadt and his photographer brother (Bierstadt Brothers) stayed. John P. Soule,[75] John B. Heywood[76] and the Kilburn Brothers[77] also produced stereographic images of scenery in the area.

highest mountain or Agiochook or Agiocochook the place of the Great Spirit or the place of the Concealed One 6 The Algonquians called the summit Waumbik white rocks 6 7 The Abenaki people inhabiting the region at the time of European contact believed that the tops of mountains were the dwelling place of the gods and so among other reasons did not climb them out of religious deference to their sanctity 8 The first European to mention the mountain was Giovanni da Verrazzano Viewing it from the Atlantic Ocean in 1524 he described what he saw as high interior mountains 9 Darby Field claimed to have made the first ascent of Mount Washington in 1642 10 Field climbed the mountain in June of that year to demonstrate to the Abenaki chief Passaconaway that the Europeans bargaining for tribal land were not subject to the gods believed to inhabit the summit a primarily political move that facilitated colonists northern expansion 8 Field again summited Agiocochook in October 1642 on an early surveying expedition that created maps of land as far as Maine which allowed people from the Massachusetts colony to identify arable coastal areas 8 A geology party headed by Manasseh Cutler named the mountain in 1784 11 The Crawford Path the oldest continuously maintained hiking path in the United States 12 was laid out in 1819 from Crawford Notch to the summit and has been in use ever since Ethan Allen Crawford built a house on the summit in 1821 which lasted until a storm in 1826 11 The second Summit House in 1904 Little occurred on the summit itself until the mid 19th century when it was developed into one of the first tourist destinations in the nation with construction of more bridle paths and two hotels The Summit House opened in 1852 a 64 foot long 20 m stone hotel anchored by four heavy chains over its roof In 1853 the Tip Top House was erected to compete Rebuilt of wood with 91 rooms in 1872 1873 the Summit House burned in 1908 then was replaced in granite in 1915 11 The Tip Top House alone survived the fire today it is a state historic site recently renovated for exhibits Other Victorian era tourist attractions include a coach road 1861 now the Mount Washington Auto Road and the Mount Washington Cog Railway 1869 both of which are still in operation 13 For forty years an intermittent daily newspaper called Among the Clouds was published by Henry M Burt at the

196 8 17Average max and min temperatures in CPrecipitation totals in mmThe summit station of Mount Washington has an alpine climate or tundra climate Koppen ET although it receives an extremely high amount of precipitation atypical for most regions with such cold weather However elevations just beneath treeline have a subarctic climate Koppen Dfc which eventually transitions to a humid continental climate Koppen Dfb near the mountain s base and the surrounding lower elevations 19 The weather of Mount Washington is notoriously erratic This is partly due to the convergence of several storm tracks mainly from the Atlantic to the south the Gulf region and the Pacific Northwest The vertical rise of the Presidential Range combined with its north south orientation makes it a significant barrier to westerly winds Low pressure areas are more favorable to develop along the coastline in the winter due to the relative temperature differences between the northeastern United States and the Atlantic Ocean With these factors combined hurricane force wind gusts are observed from the summit of the mountain on average of 110 days per year These extreme winds also contribute to the mountain s very short treeline with elevations as low as 4 400 feet being too hostile to support any plant life more than a few inches in height 20 21 Mount Washington once held the world record and still holds the Northern Hemisphere and Western Hemisphere record for directly measured surface wind speed at 231 mph 372 km h recorded on the afternoon of April 12 1934 A new wind speed record was discovered in 2009 on April 10 1996 Tropical Cyclone Olivia had created a wind gust of 408 km h 254 mph at Barrow Island off the coast of western Australia 22 Satellite and radar measurements e g of tornadoes hurricanes and air currents in the upper atmosphere do not officially compete with records for surface measurements The first regular meteorological observations on Mount Washington were conducted by the U S Signal Service a precursor of the National Weather Service from 1870 to 1892 The Mount Washington station was the first of its kind in the world setting an example followed in many other countries For many years the record low temperature was thought to be 47 F 44 C occurring on January 29 1934 but upon the first in depth examination of the data from the 19th century at NOAA s National Climatic Data Center in Asheville North Carolina a new record low was discovered Mount Washington s official record low of 50 F 46 C was recorded on January 22 1885 The official record cold daily maximum is 28 F 33 C on February 6 1995 18 Highs of 0 F 18 C or below occur on 13 days annually while lows at or below 0 F can be expected from November 17 through April 1 from December to March temperatures rise above freezing on only 15 days 18 On January 16 2004 the summit weather observation registered a temperature of 43 6 F 42 0 C and sustained winds of 87 5 mph 140 8 km h resulting in a wind chill value of 102 59 F 74 77 C at the mountain 23 During a 71 hour period from approximately 3 p m on January 13 to 2 p m on January 16 2004 the wind chill on the summit never went above 50 F 46 C 23 The official record high temperature at the summit is 72 F 22 C on June 26 2003 and August 2 1975 24 while the official record warm daily minimum is 60 F 16 C on the latter date 18 Readings of 60 F or more at the summit are seen on an average 13 5 days annually 25 The primary summit building was designed to withstand 300 mph 480 km h winds other structures are chained to the mountain 26 In addition to a number of broadcast towers the mountain is the site of a non profit scientific observatory reporting the weather as well as other aspects of the subarctic climate of the mountain The extreme environment creates strong winds and ice at the top of Mount Washington making the use of unmanned equipment problematic The observatory also conducts research primarily the testing of new weather measurement devices The Sherman Adams summit building which houses the observatory is closed to the public during the winter 27 and hikers are not allowed inside the building except for pre arranged guided tours 28 The Mount Washington Observatory was built on the summit in 1932 through a group interested in and noting the worth of a research facility at that demanding location 29 The observatory s weather data have accumulated a climate record since Temperature and humidity readings have been collected using a sling psychrometer a simple device containing two mercury thermometers Where most unstaffed weather stations have undergone technology upgrades consistent use of the sling psychrometer has helped provide scientific precision to the Mount Washington climate record 30 The observatory makes prominent use of the slogan Home of the World s Worst Weather a claim that originated with a 1940 article in Appalachia magazine by Charles Brooks the man generally given the majority of credit for creating the Mount Washington Observatory The article was titled The Worst Weather in the World even though it concluded that Mount Washington most likely did not have the world s worst weather 28 31 Image gallery Edit Mount Washington Observatory The original weathered shingle clad building is chained to the ground here covered in rime ice in early April The summit of Mount Washington is frequently obscured by clouds Precipitation Edit Due in part to its high prominence to its situation at the confluence of two major storm tracks and to the north south orientation of the Presidential Range ridgeline which it crowns Mount Washington receives high levels of precipitation averaging an equivalent of 91 2 in 2 320 mm of rain per year b with a record high for a calendar year of 130 14 in 3 305 6 mm in 1969 32 and a low of 71 34 in 1 812 0 mm in 1979 Monthly precipitation has ranged from 0 75 in 19 1 mm in October 1947 to 28 70 in 729 0 mm in October 2005 24 Large amounts of precipitation often fall in a short period of time in October 1996 a record 11 07 in 281 2 mm of precipitation fell during a single 24 hour period A substantial

mountain s other sides are more complex On the north side Great Gulf the mountain s largest glacial cirque forms an amphitheater surrounded by the Northern Presidentials Mounts Clay Jefferson Adams and Madison 15 These connected peaks reach well into the treeless alpine zone Massive Chandler Ridge extends northeast from the summit of Washington to form the amphitheater s southern wall and the incline is ascended by the Mount Washington Auto Road 15 First aid cache East of the summit a plateau known as the Alpine Gardens extends south from Chandler Ridge at about 5 200 feet 1 600 m elevation It is notable for plant species either endemic to alpine meadows in the White Mountains or outliers of larger populations in arctic regions far to the north 35 Alpine Gardens drops off precipitously into two prominent glacial cirques Craggy Huntington Ravine offers rock and ice climbing in an alpine setting More rounded Tuckerman Ravine is New England s premier venue for spring back country skiing as late as June and then a scenic hiking route 36 South of the summit lies a second and larger alpine plateau Bigelow Lawn 37 at 5 000 feet 1 500 m to 5 500 feet 1 700 m elevation Satellite summit Boott Spur and then the Montalban Ridge including Mount Isolation and Mount Davis extend south from it while the higher Southern Presidentials Mounts Monroe Franklin Eisenhower Pierce Jackson and Webster extend southwest to Crawford Notch Oakes Gulf separates the two high ridges Uses Edit Bowl of Tuckerman Ravine showing skiers above the lip The mountain is part of a popular hiking area with the Appalachian Trail crossing the summit and one of the Appalachian Mountain Club s eight mountain huts the Lakes of the Clouds Hut located on one of the mountain s shoulders Winter recreation includes Tuckerman Ravine famous for its Memorial Day skiing and its 50 degree slopes The ravine is notorious for its avalanches of which about 100 are recorded every year and which have killed six people since 1849 Scores of hikers have died on the mountain 38 in all seasons due to harsh and rapidly changing conditions inadequate equipment and failure to plan for the wide variety of conditions that can occur above tree line 39 The weather at Mount Washington has made it a site for glider flying In 2005 it was recognized as the 14th National Landmark of Soaring 40 Hiking Edit The Mount Washington Cog Railway in 2006 Motorcycles cruise the auto road Mount Washington from the Lakes of the Clouds The most common hiking trail approach to the summit is via the 4 1 mile 6 6 km Tuckerman Ravine Trail It starts at the Pinkham Notch camp area and gains 4 280 feet 1 300 m leading straight up the bowl of Tuckerman Ravine 41 via a series of steep rock steps that afford views of the ravine and across the notch to Wildcat Mountain Fatalities have occurred on the trail both from ski accidents and hypothermia Water bottles may be refilled at the base of the bowl 2 1 miles 3 4 km up the trail at a well pump near the Hermit Lake Shelters which offers snacks toilets and shelter 42 At the summit is a center with a museum gift shop observation area cafeteria and the Mount Washington Observatory Other routes up the eastern slopes of the mountain include the Lion Head Boott Spur Huntington Ravine and Nelson Crag trails as well as the Great Gulf Trail ascending from the northeast Routes from the western slopes include the Ammonoosuc Ravine and Jewell trails and the Crawford Path and Gulfside Trail coincident with the Appalachian Trail from the southwest and from the north respectively 43 There are many differences between climbing Mount Washington in summer and climbing it in winter There are no public facilities on the summit in winter 44 In the winter months the most common route is the Lion Head Winter Route which begins on the Tuckerman Ravine Trail but then turns north to ascend up to Lion Head at elevation 5 033 feet 1 534 m The winter route variation is recommended to help climbers avoid avalanche danger 45 Exactly where the route turns from the Tuckerman Ravine Trail depends on the snow conditions If the amount of snowfall has not been significant the Lion Head Summer Route may be open After hiking 2 3 miles 3 7 km from the visitor center in Pinkham Notch the trail will take a right turn onto the Lion Head Summer Route If there has been enough snow accumulation on the summer Lion Head Trail the Forest Service will open the Lion Head Winter Route which turns off after approximately 1 7 miles 2 7 km 45 Cog railway Edit Main article Mount Washington Cog Railway Since 1869 the Mount Washington Cog Railway has provided tourists with a train journey to the summit of Mount Washington 46 It uses a Marsh rack system and was the first successful rack railway in the US 47 Races Edit Every June the mountain is the site of the Mount Washington Road Race an event that attracts hundreds of runners In August the Mount Washington Auto Road Bicycle Hillclimb a bicycle race takes place along the same route as the road race 48 The hillclimb s notable contestants include former Tour de France contender Tyler Hamilton 49 On August 7 1932 Raymond E Welch became the first one legged man to climb Mount Washington 50 An official race was held and open only to one legged people Mr Welch climbed the Jacob s Ladder route and descended via the carriage road At the time of his climb he was the station agent for the Boston amp Maine Railroad in Northumberland New Hampshire 50 The mountain is also the host to one of the oldest car races in the country the Mount Washington Hillclimb Auto Race which has been held on and off since 1904 Travis Pastrana set record ascents in 2010 2014 2017 and 2021 driving a Subaru WRX STi to a record of five minutes and 28 67 seconds 51 52 53 In 2014 EVSR created by Entropy Racing was the first electric car to compete at Mt Washington with an official time for driver Tim O Neil of seven minutes and 28 92 seconds 54 Stitched 360 degree panorama from around the summit Panorama of the buildings on the summitTransmission facilities Edit FM broadcasting station WMTW s ice covered Mount Washington transmitter site in 1944 55 Due to its status as the highest elevation in the northeast United States the top of the mountain is a popular site for stations that require transmission ranges over a broad territory but which operate on frequencies that are generally limited to line of sight coverage In 2003 it was reported that the summit was the site used for three commercial radio stations and dozens of state federal and private agencies including the state police 56 Use of the mountain summit as a transmitter site dates to the 1930s At this time investigations were begun into establishing radio stations broadcasting on Very High Frequency VHF assignments above 30 MHz Reception of stations operating on these frequencies tended to be limited to line of sight distances so operating from the top of Mount Washington was ideal for providing maximum coverage As of 1938 it was reported that at least five experimental stations were located on the mountain 57 The most prominent of the early experimental stations was W1XER originally an Apex radio station licensed to the Yankee Network that was moved from Boston to the mountain in 1937 and initially used to relay meteorological information from the weather observatory With the aid of Edwin H Armstrong the station was converted from an AM transmitter into an FM broadcasting station although the conversion process turned out to be an arduous undertaking 58 and W1XER did not start broadcast programming on a regular schedule until December 19 1940 59 This station s facilities included construction of the original broadcast tower the Yankee Building housing the crew and transmitter equipment and the first power house building Commercial broadcasting commenced on April 5 1941 60 initially with the call sign W39B 61 Effective November 1 1943 the station call sign was changed to WMTW 62 and in late 1946 the call letters were changed again to WMNE WMNE ceased operations in late 1948 due to excessive maintenance costs and concern that a mandatory frequency change to the new FM high band would cause an unacceptable decrease in transmission range 63 In 1954 WMTW channel 8 licensed to Poland Spring Maine constructed a TV tower and transmitter and began operations from the mountain including local forecasts by now retired WMTW transmitter engineer Marty Engstrom 64 This station relocated its transmitter away from the mountain in 2002 due to concerns that a mandated switch from analog to digital transmissions would result in insufficient coverage if the transmitter remained at the mountaintop 65 There are currently two FM stations located at the mountain 1958 saw the construction of WMTW FM 94 9 MHz now WHOM A second station WMOU now WPKQ moved to the summit in 1987 installing transmitters in the Yankee building and constructing a new broadcast tower behind the building which is the tallest structure on the summit WHOM and WMTW TV shared a transmitter building which also housed the generators used to supply electrical power to the various facilities atop the mountain However on February 9 2003 a major fire broke out in the generator room of the transmitter building which had become the property of the state only a year earlier when WMTW left the summit The fire destroyed the building including WHOM s transmitters as well as the summit s main generators and also spread to the adjacent Old Yankee Power House building which housed the emergency generator destroying that building also and disrupting all power to the summit Temporary generators had to be transported up the mountain to restore power to the observatory and to the Yankee building which houses important public safety communications equipment A makeshift generator room was constructed underneath the canopy of the Sherman Adams building across from the public entrance to replace the destroyed buildings The makeshift generator room was later made permanent when power cables were installed in 2009 delivering grid power to the summit for the first time The original Armstrong tower still stands today The Yankee Building also remains and continues to serve as a communications facility housing equipment for numerous tenants including cellular telephone providers and public safety agencies The old sign from the destroyed Old Yankee Power House building was placed above the doorway to the new generator room WHOM subsequently built a new transmitter building on the site of the old power building and also installed a new standby antenna on the Armstrong tower For the first time since 1948 the Armstrong tower was used for broadcasts 66 The National Weather Service NWS forecast office in Gray Maine operates NOAA Weather Radio station KZZ41 on 162 5 MHz from the summit of Mount Washington The NWS coverage map indicates that it can be heard throughout most of New Hampshire western Maine northeast Vermont and portions of southern Canada During very clear conditions KZZ41 has the potential to reach the majority of northern Massachusetts including some northern areas of Greater Boston and much of the North Shore as well as the majority of Vermont and Maine 67 In June 2008 the possibility of television returning to Mount Washington arose with the filing by New Hampshire Public Television to move WLED TV from its current location near Littleton to the old WMTW mast on top 68 69 Deaths EditMain article List of people who died on the Presidential Range As of 2019 more than 161 people had died in the Presidential range since record keeping began in 1849 70 Author Nicholas Howe has detailed many of the fatalities on this mountain in his book Not Without Peril published in 2000 and updated in 2009 71 The foreword to the 2009 edition states that many of the deaths over the past 150 years can be attributed to poor planning and lack of understanding of the difference in weather between Boston and the mountains The latter are farther north farther inland and much higher than the city William Buckingham Curtis often posthumously called the father of American amateur athletics died from exhaustion on June 30 1900 near Lakes of the Clouds Hut during a snowstorm 72 Artistic tributes EditMount Washington has been the subject of several famous paintings part of a New England school of art known as White Mountain art 73 Inspired by the Hudson River School of landscape painting a number of artists during the Victorian era ventured into the White Mountains in search of natural subjects 74 Train service in the area spurred increased tourism and the construction of the Glen House where Albert Bierstadt and his photographer brother Bierstadt Brothers stayed John P Soule 75 John B Heywood 76 and the Kilburn Brothers 77 also produced stereographic images of scenery in the area Mount Washington from Glen House in a stereographic image by John P Soule Ferdinand Richardt 1857 Benjamin Champney John F Kensett 1869 Albert Bierstadt 1858 See also
