Aeolis Buttes

This image from NASA's Mars Global Surveyor shows dozens of dark slope streaks, created by dry avalanches of dust, extend from toward the base of dust-covered buttes. Large, dust-covered, windblown ripples surround the group.

21 April 2006
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a group of dust-covered buttes in the Aeolis region of Mars. Dozens of dark slope streaks -- created by dry avalanches of dust -- extend from a variety of elevations toward the base of each butte. Large, dust-covered, windblown ripples surround the group and occupy some of the low-lying areas between individual buttes.
