Upper Antelope Canyon, outside of Page, AZ
This is one of the few slot canyons that survived being flooded by Lake Powell and the Glen Canyon Dam, and is probably the most famous slot canyon in the world.
Upper Antelope can only be reached on a guided Navajo tour, due to a flash flood that took the lives of 12 tourists in 1997. It is narrow at the top and widens as it descends. This allows the little bit of sun that gets in to bounce around all the curves and lines in the walls. It is this reflected light that makes the canyon come alive with glowing reds and oranges, and also allows sunbeams to come in, Antelope Canyon's most famous feature.

This is about as close to symmetrical as you can get in Antelope Canyon. To give you some idea of how crowded it is in there, there were about 5 other photographers around me shooting the same beam, and a 20-person tour group behind us, waiting for our 30 second exposures to finish before they went on their way.
Wow..... my first DD. It's all too much you guys, really. I just want to thank everyone, especially those that I've gotten to know in my relatively short time here.
Also, I've been getting alot of requests to change the frame, so I think I just might, though I don't really have the time at the moment. Maybe in the next few days.
