   Summary Author:  James Denton

   The photo above provides a unique look into the  formation processes
   of a layered rock feature in the  Mojave Desert. Similar to how warm
   snow will clump together and roll down a steep hill to create a
    pinwheel, hot freshly fallen  volcanic ash can do the same-
   albeit on a much grander scale. Shown with a person for scale, these
   layers slightly differ in size, but are generally several feet thick.
   Photo taken December 16, 2021.

   Photo details: TINNO U304AA, f/2.2, 1/317 second exposure, ISO-118
