It is easy to go from one spectacular natural monument to another in Wyoming. The lions share of the mammoth Yellow Stone National Park lies in the western part of the state. And next door in Jackson Hole, one of the most spectacular mountain ranges in America – the Grand Tetons – spear the sky with their jagged peaks. And to the east there is the Devil’s Tower, which is a couple of hours’ drive away from South Dakota’s Mt. Rushmore.
