Those of you who have been to the Antelope Slot Canyons, outside of Page, Arizona, know what a treat these places are for the eye. I have been to the upper slot, but this is my first time at the lower. It's much more compact, but walkable, and offers less in the form of light beams, but much, much more in the form of intricate wall patterns and colors. Two more days to go here.

Wonderful image David of a magical place. Only suggestion I can make is about the middle "wave peak" merging with the change in rock behind it. A bit higher perspective would have eliminate this. (Note that I always see these things way after the fact, including my own photos.)
