Then we drove through the Escalante Grand Staircase National Monument. It is a huge park (over 2,600 square miles), with no actual “center.” We stopped at the Head of the Rocks Overlook to admire the view. Though you can’t really spot anything that looks like what you think of as a ‘staircase’ (the cliffs of the various layers represent risers in a staircase), it is a fascinating formation containing clues to the geological history of the Earth for a period of more than 200 million years.
