THEMIS: Windstreak on Daedalia Planum

Windstreak on Daedalia Planum (THEMIS_IOTD_20161026)THEMIS Image of the Day, October 26, 2016. The “tail” behind the crater at the top of this VIS image is called a windstreak. This feature is formed by winds blowing over, in, and around the crater. Turbulence in the wind will erode or deposit fine materials, creating the windstreak. Windstreaks form on the downwind side of the crater, and here the streak indicates winds from the ESE. The small hills below the windstreak are small volcanic constructs. This image is located in the extensive lava plains called Daedalia Planum.
