“Along a Precarious Trail” by LYLE GLASS.

On a hot summer day, after quenching their thirst at a natural spring, about the only water available in this dry spell, a remuda of wild horses leave the spring and head out, single file along a precarious trail on the side of the butte. We did get an inch to an inch and a half of rain since this image was taken, and the watering holes have water in them.
