Blue John Canyon came to international attention in 2003 as the place where the outdoorsman Aron Ralston was forced to amputate his own right forearm with a multi-tool after it became trapped by a boulder. Ralston's entrapment was described in his autobiography Between a Rock and a Hard Place and was depicted in the 2010 film 127 Hours.
Antelope Canyon is a slot canyon in the American Southwest. It is on Navajo land east of Page, Arizona. Antelope Canyon was formed by erosion of Navajo Sandstone, primarily due to flash flooding and secondarily due to 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, 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 October 30, 2006, that lasted 36 hours, and caused the Tribal Park Authorities to close Lower Antelope Canyon for five months.
