There were some other photographers there and one guy in particular cracked me up.... he was running around with his camera like a chicken with his head cut off. I half expected him to trip and fall into the canyon. Ironically he - and a couple other photographers - left before the light got really good. After that there were just two of us left photographing... me and a very nice guy (and good photographer) from northern Utah named Bob Hills. Be sure to check out his website www.bobhillsphotography.com .
Here are a few of the hundreds of photos I took at the arch.
