Fossil Mountain is a prominence that is located on a spur in the Western Grand Canyon, in Coconino County, Arizona. The summit of this prominence has a summit elevation of 6,729 ft (2,051 m) and lies about 1 mi (1.6 km) southeast of the Grand Scenic Divide, and 1 mi (1.6 km) west of Havasupai Point. This summit lies almost level with the surface of the adjacent tableland of the South Rim, the forested Kaibab Plateau.[4]

As seen in the above photograph, Fossil Mountain exhibits a large cliff of Kaibab Limestone. The southwest slope of Fossil Mountain is a highly vegetated (trees), and high angle slope to the prominence. Below the 350 ft (110 m) cliff of Kaibab Limestone is about ~250 ft (76 m) of vegetated slope-forming Toroweap Formation. The Toroweap Formation sits upon a ~500 ft (150 m) cliff-forming, Coconino Sandstone, very vertical, and uneroded, (northeast face of Fossil Mountain, overlooking the canyon). The Coconino Sandstone sits on large slopes of vegetated Hermit Formation.[4][5]
