Antelope Canyon - Antelope Canyon was formed by erosion due to flash flooding and also wind.
Antelope Canyon - 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.
Antelope Canyon - 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.
