Dune, Interdune, And Scrollwork Ridges 照片檔

The flat area of an interdune in which grow clumps of grass in between taller dunes at White Sands National Park in New Mexico. The ridges are known as scrollwork ridges and are the hardened/fossilized remnants of barchan dunes that have been moved along by the wind. Overhead is a cloudless, mainly blue sky that is sort of hazy due to the wind picking up loose sand grains.
