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.
Photos of the Fossil Mountain prominence, a large cliff of Kaibab Limestone, can be seen at Summitpost. [4] 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.
