I am not that familiar with southern Utah but if you're any where near Arches National Park, I would SRTONGLY suggest you check it our overnight. My understanding is that some of the arches need to be shot in early morning light and you may have a short hike to get to them at the right time so plan accordingly. I think the big question is not how much to see but how much time you have to see what you can. Lets us all know your plan so we can root you on! Magick Michael
