This isolated butte is an erosional remnant composed of Permian Kaibab Limestone and Coconino Sandstone.[4] This sandstone, which is the third-youngest stratum in the Grand Canyon, was deposited 265 million years ago as sand dunes. According to the Köppen climate classification system, Mount Sinyella is located in a Cold semi-arid climate zone.[5]
History
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 Havasupai chief 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]
