THEMIS: Wind, dust, and gravity in Medusae Fossae

Wind and gravity in Medusae Fossae (THEMIS_IOTD_20180410)THEMIS Image of the Day, April 10, 2018. This VIS image is located in Medusae Fossae. Along the cliffside several dark streaks are visible.

It is thought that these streaks mark the location where downslope movement of material has removed some of the dust that coats every surface of Mars, and revealed the rocky surface beneath the dust.

The surface of the rest of the image appears to have been modified by wind erosion, which has created the aligned small hills and ridges.
