PIA03547: Dust-covered Flow


Dust-covered Flow

Caption:

17 November 2005
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows an ancient lava flow surface near the volcano, Ascraeus Mons. The volcanic material has been completely covered by thick accumulations of dust. An earlier accumulation of dust or ash was eroded by wind to form the sharp, nearly triangular hills and ridges seen on top of the flow surfaces. A small impact crater with bouldery ejecta has formed on top of the old flow material in the southern (lower) quarter of the image.
