MGS MOC Release No. MOC2-391, 14 June 2003

This March 2003 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dark sand dunes near the center of Schaeberle Crater, located at 24.6°S, 310.3°W. The steepest slopes on the dunes point toward the left/upper left (northwest), indicating that, when the dunes were active, the dominant regional winds blew from the right/lower right (southeast). The dunes today, however, have a somewhat stunted and sculpted appearance, which suggests that in the most recent part of their history, they have been somewhat eroded. This image covers an area 3 km (1.9 mi) wide and is illuminated from the upper left.
