Situated on Navajo land in the Lake Powell Navajo Tribal Park, Arizona, Antelope Canyon is one of the most photographed slot canyons in the United States. This natural wonder was formed by water rushing through rock over the course of millions of years. It’s made up of two separate sections: the deep (but narrow) Upper Antelope Canyon (also known as Spiral Rock Arches) and the Lower Antelope Canyon (Hasdeztwazi).
