Navajo Upper Antelope Canyon

Navajo Upper Antelope Canyon is a slot canyon in the American Southwest, on Navajo land east of Lechee, Arizona. It includes five separate, scenic slot canyon sections, referred to as Upper Antelope Canyon (or The Crack), Rattle Snake Canyon, Owl Canyon, Mountain Sheep Canyon, and Lower Antelope Canyon (or The Corkscrew).

The Navajo name for Upper Antelope Canyon is Tsé bighánílíní, which means 'the place where water runs through the (Slot Canyon) rocks'. Lower Antelope Canyon is Hazdistazí (called "Hasdestwazi" by the

Navajo Parks and Recreation Department), or "spiral rock arches". Both are in the LeChee Chapter of the Navajo Nation. They are accessible by “Navajo” guided tour only.

Antelope Canyon was formed by the erosion of Navajo Sandstone due to flash flooding and other sub-aerial processes. Rainwater, especially during monsoon season, runs into the extensive basin above the slot canyon sections, picking up speed and sand as it rushes into the narrow passageways. Over time the passageways eroded away, deepening the corridors and smoothing hard edges to form characteristic "flowing" shapes.
