Antelope Canyon is probably one of the most beautiful and unique places I've ever been to date. Sitting on land owned by the Navajo Nation, entry into the slot canyons is exclusively through guided tours, in part because rains during monsoon season can quickly flood the 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. 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. We were up before dawn to get an early tour before the hoards of people were rushed in kicking up dust and making photographing this miracle almost impossible. I guess the early bird does get the worm.
