Angels Gate is a Шаблон:Convert-elevation summit located in the Grand Canyon, in Coconino County of Arizona, United States.[1] It is situated Шаблон:Convert due north of the Grandview Point overlook on the canyon's South Rim, Шаблон:Convert west of Vishnu Temple, and Шаблон:Convert southeast of Zoroaster Temple. Topographic relief is significant as it rises over Шаблон:Convert above the Colorado River in three miles. Angels Gate is the place in Paiute mythology where the gods would return to Earth by descending from the shadow world above.[2]

George Wharton James applied the "Angel Gate" name to this geographical feature in his book, In & Around the Grand Canyon, in 1900. This feature's name was officially adopted in 1906 by the U.S. Board on Geographic Names.[1] Angels Gate has four peaks composed of Coconino Sandstone. The main highest summit and three spires are known as "Snoopy and his Doghouse" for a resemblance to Snoopy, and the first ascent was made April 1972 by Chuck Graf and Dave Ganci.[3][4] According to the Köppen climate classification system, Angels Gate is located in a cold semi-arid climate zone.[5]

Geology

The summit of Angels Gate is composed of remnant, cliff-forming, Permian Coconino Sandstone.[6] 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, Cambrian Tonto Group, and finally Proterozoic Unkar Group at creek level and Granite Gorge.[7] Precipitation runoff from Angels Gate drains south to the Colorado River.

Hawkins Butte is a Шаблон:Convert-elevation butte attached at the southwest end of Angels Gate.[8] It was officially named in 1932 after William "Billy" Robert Hawkins, the hunter and cook for John Wesley Powell's 1869 expedition down the Colorado River through the Grand Canyon.[9] It is primarily composed of exposed cliffs of Redwall Limestone overlaying Tonto Group.
