Antelope Canyon is located in Arizona on Navajo land.
It has been formed by flash flooding over the years, that has eroded the sandstone.
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 are eroded away, making the corridors deeper and smoothing hard edges in such a way as to form characteristic ‘flowing’ shapes in the rock.
Flash flooding is still a danger to visitors today with the last major flash flood occurring in 2006.
Tourists may only visit the canyon with a guide because of this flood danger.
There are two sections of the canyon: Upper Antelope Canyon (also called The Crack) and Lower Antelope Canyon (also called The Corkscrew). The Navajo call the Upper Canyon Tse’ bighanilini, meaning “the place where water runs through rocks.” The Lower Canyon is called Hasdestwazi, meaning “spiral rock arches.”
The canyons can both be found within the LeChee Chapter of the Navajo Nation, in Lake Powell Navajo Tribal Park. There are entrance fees for both canyons, and these fees provide the Navajo Nation with much needed income.
Photography within the canyons is difficult due to the wide exposure range (often 10 EV or more) made by light reflecting off the canyon walls.**
