Antelope Canyon is the most visited slot canyon in the southwestern United States. It consists of Upper Antelope Canyon and Lower Antelope Canyon and is located near Page, Arizona. It was formed by Antelope Creek, a stream about 30 km long and rarely flowing after torrential rains in its area of origin in the Mormon Ridges.
In addition to the two slot canyons, a side canyon flooded by Lake Powell is called Antelope Canyon; it is navigable by boats for a few miles.
