   Summary Author:  Stan Wagon

   Shown above is a remarkable  lacy formation in the  Navajo
   sandstone of  Vermillion Cliffs, Arizona. More detail can be seen in
   the bottom photo. Tens of thousands of years ago, a thin (about 3 mm)
   layer of sand here was compressed more than its surroundings. This
   “ compression band” became a very thin curtain-like stone feature,
   less permeable to water and therefore more resistant to erosion.

   Photo details:  SONY A6500 camera; 14 mm lens; 1/200 second exposure;
   f13; ISO 250.
