Verna and I were visiting Arches National Park on July 21, 2008. This was when we were still considering retirement in about a year from then and deciding to use up some of our accrued vacation time.
The object in the background is a sandstone hill where three arches-in-progress graphically show the evolution of arches sculpted by wind and rain. There is a mostly completed arch on the left side with a just beginning stage in the middle and an intermediate stage arch-in-the making on the right.
