Antelope Canyon Near the Grand Canyon, USA. Antelope Canyon in Arizona on the Navajo Indian Reservation is the most photographed slot canyon in America. It's a sacred and spiritual place. Serene and mystical. A quiet reverence. A special work of art created by nature. An unimaginable blend of glowing pastel colors made brilliant by cascading beams of sunlight that illuminate an artful collection of sculpted sandstone in infinite shape and form.
