Wind erosion (THEMIS_IOTD_20180717)THEMIS Image of the Day, July 17, 2018. Winds in this region have modified the surface, carving valleys into a poorly cemented material. The winds in this region blew toward the northeast. (Note: north is to the top of the image, and sunlight is coming from the right.) These linear valleys are called yardangs.
