THEMIS: Wind etching

The wind is whittling knife (THEMIS_IOTD_20160609)THEMIS Image of the Day, June 9, 2016. Today’s VIS image is located near Memnonia Sulci, on the edge of Lucus Planum. The material at the top and left side of the image has been eroded by the wind to form features called yardangs. Yardangs form in a poorly cemented material where the wind cuts linear valleys, removing some of the material and leaving parallel ridges behind. The direction of the ridge/valley is aligned with the wind direction.
