There are several slot canyons in Arizona & Utah to see, all have unique views. Both Upper and Lower Antelope Canyons, in Paige AZ, are some of the most popular due in part to publicity from Peter Lik's $6M print sale and Microsoft file purchase for several million to use on their screen savers. Once there, you'll be in awe of the sandstone shapes and the effects light has in different areas, not to mention the deceiving depth (~120' deep) all created by rushing water & sand in flash flooding. These slot canyons were the high point of the trip.
As you go through, the tour guides will point out different symbols. Personally, i was too busy taking photos to write down each one, but I do remember a few. You can see some by looking straight up as well as straight ahead, some you have to get at a certain angle. They are in the gallery below, can you find the figures?
