Fossil Mountain is a 6,729-foot-elevation summit located in the Western Grand Canyon, in Coconino County of northern Arizona, Southwestern United States. It is situated ~1.5 miles due east of Mount Huethawali, about 1.0 miles southeast of the Grand Scenic Divide, and 1.0 mi west of Havasupai Point.

The Fossil Mountain prominence is a massif-remainder cliff of Kaibab Limestone, and stands above a tableland of the South Rim, a forested plateau of Kaibab Limestone.

Geology

Photos of the Fossil Mountain prominence, a large cliff of Kaibab Limestone, can be seen at Summitpost. The southwest slope of Fossil Mountain is a highly vegetated (trees), and high angle slope to the prominence.

Below the ~350 ft cliff of Kaibab Limestone is about ~250 ft of vegetated slope-forming Toroweap Formation. The Toroweap sits upon a ~500  cliff-formed, Coconino Sandstone, very vertical, and uneroded, (northeast face of Fossil Mountain, overlooking the canyon). The Coconino sits on large slopes of vegetated Hermit Formation.
