Antelope Canyon was formed by erosion of Navajo Sandstone, priamarily due to “flash floods” and secondarily due to sub-aerial processes. Rainwater, especially during the monsoon season, runs into the extensive basin above the slot canyon section, picking up speed and sand as it rushes into the narrow passageway. Over time, the passageway eroded away, making the corridors deeper and smoothing hard edges in such a way as to form characteristic “flowing” shapes in the rock. Flooding in the canyon still occurs. A flood occurred on 30th October, 2006, that lasted 36 hours, and caused the Tidal Park Authorities to close lower Antelope Canyon for 5 months.
