A Lacy Curtain of Stone

May 31, 2021


Photographer: Stan Wagon

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.

Vermilion Cliffs National Monument, Arizona Coordinates: 36.8625,
