This April 2004 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a dark wind streak on the lee (downwind) side of a small meteor impact crater in western Daedalia Planum. The substrate in this region consists of large lava flows (larger than the image shown here). The winds responsible for the streak came from the east/northeast (right). This picture is located near 15.4°S, 138.1°W, and covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the upper left.
