Mount Huethawali is a 6,281-foot-elevation (1,914-meter) summit located in the Grand Canyon, in Coconino County of northern Arizona, US. It is situated 3.5 miles due east of Explorers Monument, 1.5 mile west of Grand Scenic Divide, and immediately southwest of Huxley Terrace. Surrounded by Garnet, Evolution, and Bass Canyons, Huethawali rises over 800 feet (240 meters) above Darwin Plateau, and over 4,000 feet higher than the nearby Colorado River.
The summit dome is composed of cream-colored Permian Coconino Sandstone. This sandstone, which is the third-youngest stratum in the Grand Canyon, was deposited 265 million years ago as sand dunes. Below the Coconino Sandstone is reddish, slope-forming, Permian Hermit Formation, which in turn overlays the Pennsylvanian-Permian Supai Group. Further down are strata of the cliff-forming Mississippian Redwall Limestone, Cambrian Tonto Group, and finally Proterozoic Unkar Group at river level.
According to the Köppen climate classification system, Mount Huethawali is located in a cold semi-arid climate zone.
