Antelope Canyon

Lower Antelope Canyon from the surface, near its exit, on an August evening. From up here the whole canyon is just a dark seam winding through a flat expanse of pink sandstone, easy to walk past without noticing. That contrast is the point of the photo. Upper is entered through a cliff face at ground level, while Lower is a crack in open ground that you climb down into, and the light inside depends on the sun finding its way down that thin gap.
