This past weekend we went to Antelope Canyon which is in Page, Arizona near Lake Powell. There are incredible slot canyons that tower more than 130' overhead in many places. The light does some incredible things inside the canyons which are only shoulder-wide in some sections and over 20' wide in others.
And here we all are at the back entrance to one of the canyons . . . (from L to R: Deb, Jim, Liz, myself)
