Antelope Canyon, also called Corkscrew Canyon - slot canyon in the Arizona, includes two separate canyon sections: Upper Antelope Canyon and Antelope Canyon or The Corkscrew. It was created as a result of erosion Navaho sandstone, which is malleable, so that the water easily forms the characteristic grooves and recesses with rounded edges. In the canyon there are flash floods, so sightseeing is dangerous and it is possible only with a guide. 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, making the corridors deeper and smoothing hard edges in such a way as to form characteristic flowing shapes in the rock. Canyon is a very popular location for photographers and sightseers.
