Like a sponge, dunes soak up every drop of rain that falls on them. No water runs off dunes, and since the top several inches of dry sand insulate moist sand beneath, little water evaporates. Even during hot, rainless summers, when the air temperature is 100F and the sand surface is 140F, the sand is cool and moist just six to twelve inches below the surface.” —Dune Country
