Arches National Park was hot. We got there just in time for the hottest part of the day. Still beautiful. Alien. Did I mention hot?
We only saw a fraction of the thousands of completed arches. The amazing thing is, we saw dozens of new arches forming in the rocks. (There are probably hundreds or thousands of them developing.) As the current arches erode away, new ones will take their place. This location will have arches for thousands of years.
