The Antelope Canyon really lives up to all the hype photography fellows preach around. On a *very* crowded day - highly unusual according to many of the guides there - with groups entering the canyon every half an hour, I actually started out thinking that I wouldn't be able to enjoy it , much less take some photos I'd like. It was one of the highlights of my road trip a few weeks ago along the SW USA. It is a stunning location, and well worth a visit. I love the shapes, the shades and curves all over the place. Treacherous flash floods rush down the Antelope Canyons and smoothly erode the rock walls, leaving a an awesome natural monument to appreciate. I arrived there near high noon, which is not the best hour to visit the Lower Antelope Canyon, in my opinion. The canyon is quite wide at the top in some sections and those are very highly exposed, making it difficult to photograph properly. (I didn't get to visit the Upper one, but to get those light rays you do need to go at that time)
