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 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]
