Arches National Park, Utah
Woke up really early, packed up the car and drove to arches before it opened. We spent some time in the visitors center learning about the arches formation ( the oceans flooding and evaporating leaving salt beds for miles piling sand on top Fromm erosion and wind. The sand hardened to rock and water eventually seeped through resolving the salt creating cracks in the rock that eventually gave way to form arches... They think....Of course this process took millions...
