Antelope Canyon is an amazing sight. The narrow slot canyons of sandstone are breathtaking to walk through. If you are there at the right time of day, at the right time of year, and in the right place, you will be treated to a spectacular light show as rays of light pierce down into the canyon. The sandstone glows as if it's on fire for just a few minutes as the sun passes directly overhead. Photo © copyright by Luke Tingley.
