Aloha,
I went, I got a great shot which I will most likely never publish, arrived a couple of hours early, there was me and a very grumpy guy from Oregon and an Italian guy.
By the time the sunrise occurred there were 30-40 people crammed around the arch, three rows deep. By the time the colors peaked, I backed out of the pile and got back away up on the rise, it was just too much so many people coming away everyday with a similar/same shot.
I so badly want to go back to Antelope canyons as well, but just so many people are shooting there now. At least with Antelope canyon, there is a near limitless ability to compose shots.
At Mesa Arch, your chance of variance is very limited, as the shot is the shot.
Its like you just chalk that off a list of must have shots...
And I'm not saying the posted shot is not good, its just like every other shot, but not as wide so, you don't even get the whole view of the arch..i
