Шаблон:Short description Шаблон:Infobox mountain
Comanche Point is a Шаблон:Convert summit located in the Grand Canyon, in Coconino County of northern Arizona, US.[1] Part of the Palisades of the Desert, Comanche Point is the high point on the canyon's less-visited East Rim, and is four miles north-northeast of Desert View Point, its nearest higher neighbor. Topographic relief is significant as it towers Шаблон:Convert above the Colorado River in 1.5 mile. Comanche Point was named in 1900 by George Wharton James for the Comanche, a Native-American nation from the Great Plains, in keeping with a practice of naming the points on the canyon's South Rim for Native American nations.[2] This geographical feature's name was officially adopted in 1906 by the U.S. Board on Geographic Names.[1] According to the Köppen climate classification system, Comanche Point is located in a Cold semi-arid climate zone.[3] On September 27, 1994, the tabloid Weekly World News ran an outlandish cover story that wreckage of a 4000-year-old UFO had been found in limestone rubble near the base of Comanche Point.[4]
Geology
The summit of Comanche Point is composed of Kaibab Limestone overlaying cream-colored, cliff-forming, Permian Coconino Sandstone.[5] The sandstone, which is the third-youngest of the strata in the Grand Canyon, was deposited 265 million years ago as sand dunes. Below the Coconino Sandstone is slope-forming, Permian Hermit Formation, which in turn overlays the Pennsylvanian-Permian Supai Group. Further down are strata of Mississippian Redwall Limestone, and Cambrian Tonto Group.[6] Precipitation runoff from Comanche Point drains into the nearby Colorado River.
