White Sands National Monument

 

Saltation is a process by which the winds move the small sand grains by bouncing then along the surface.  This creates interesting and beautiful patterns of ripples on the dune surface.  Large sand grains are stuck by saltating grains and slowly roll forward advancing the dune – this process is known as “surface creep”.  As Ashley was photographing one of the dunes, I witnessed the actually “movement” of the “surface creep” process—I love seeing nature at work!
