We saw a number of great arches last week on our national park trip. This is the first we came across and it was something. Hickman's Arch is located in Capitol Reef National Park and it is a massive arch that you are allowed to climb around and walk under. Basically, these rock arches form when underlying salt domes wear out and are washed away by water, leaving the rock cap behind. At several times in the distant past this area was under a huge inland sea and the salt was left behind as the seas evaporated, forming an arch.
