This is a very resilient world we live in, and the desert has many examples of that.  When I saw this week’s challenge, one of the first places I thought of was the White Rim in Canyonlands National Park, Utah.  It’s hard to fathom the resiliency in this pillar of sandstone which remains standing while everything around it has eroded away.  This formation was once part of a long isolated wall similar to those in the background, yet still standing after many thousands (or perhaps millions) of years.
