Powell Plateau (Arizona)

Powell Plateau, named for geologist and explorer John Wesley Powell, is a 7,661-foot-elevation plateau-summit located in western Grand Canyon, about 13 mi northwest of Grand Canyon Village in Coconino County of northern Arizona, USA. Being a large plateau. (~300 acres, 0.47 mi²), the plateau causes a large west-northeast-north excursion of the west-flowing Colorado River, caused by the southwest arm of the plateau. There is a slightly-southeast trending arm, and the main plateau then trends north to higher elevations.
