Antelope Canyon

Inside Upper Antelope Canyon on a September morning, with no beam in sight. The light here is all bounce: sun striking the upper walls reflects down through the slot, so the curves nearest the opening go pale cream and the deeper folds sink into rust and brown. This is what most of a visit actually looks like, beams or not, and it is the reason a fall or winter tour is still worth taking. The rock itself began as desert sand dunes that hardened into Navajo Sandstone, which is where those fine flowing lines come from.
