Wallace Butte is a -elevation summit located in western Grand Canyon, in Coconino County, Arizona, Coconino County of northern Arizona, Southwestern United States, United States. It is located on the South Rim, about 1.0 mile northwest of the Grand Scenic Divide across Bass Canyon. Wallace Butte is 1.73 miles northeast of Mount Huethawali, and the butte lies about 3/4 mile south of the west-flowing Colorado River. Geology The large Huxley Terrace (photo), is composed of the Supai Group – 4 units. Notably, rock units 4 and 2 are cliff-formers, and the entire Supai Group sits on the cliff-former (and platform-former) of the Redwall Limestone. For Wallace Butte, geologically it is a cliff and slope-former remainder – of Supai Group units 2 and 1 (Manakacha Formation, Watahomigi Formation). The cliffs of the Manakacha protect the slope-former below; (with the height of 349 ft, the landform is triangular, thin, and ~350 ft long, by ~150 ft wide); (See here:) bo ...

Mount Huethawali
Mount Huethawali is a 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 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 se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
