Lower Antelope Canyon is near Page Az. I have spent almost two full days there, photographing the amazing curves and textures and colors in this slot canyon. I found the photography police to be much better at Lower Antelope, rather than Upper. I don't know if that's still true. This remarkable feature is unfortunately no longer there, washed away in a typical flash flood. It is on a Navajo reservation.
