Mount Sinyella is a 5,441-foot-elevation (1,658 meter) summit located in the western end of Grand Canyon National Park, in Coconino County of northern Arizona, US.[3] It is situated 1.7 mile (2.7 km) north-northwest of Uqualla Point, and four miles (6.4 km) southeast of Boysag Point, at the mouth of Havasu Canyon. As the high point of Sinyella Mesa, it towers 1,200 feet above the mesa, and 3,600 feet above the nearby Colorado River which is 1.5 mile to the northwest.
This butte's name was adopted as Mount Sinyala in 1932 by the U.S. Board on Geographic Names. In 1988, the board officially revised it to the present spelling, Sinyella.[3] It was named by the American conservationist Charles Sheldon for Judge Sinyella (1853–1923), a prominent Havasupaichief who Sheldon hired as a guide to show him the canyon in 1912.[3][6] "It is interesting to go with him [Sinyala], he knows every foot of the country" noted Sheldon.[7] The local native inhabitants called it "Week-eel-eela" which is said to mean "stick sitting up", also their general term for any butte.[8]
The first ascent of the summit was made April 11, 1960, by Don Myers, Mike Sherrick, Jim Wilkerson, and Bill Amborn via the north face.[9] The second ascent was made by Dave Ganci and Jerry Robertson, May 3, 1969.[10]
