PIA04509: Chasma Boreale Dunes


Chasma Boreale Dunes

Caption:

MGS MOC Release No. MOC2-354, 8 May 2003

In this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image, wind has streaked a field of defrosting sand dunes in Chasma Boreale in the martian north polar region. Dune slip faces--the steep slope formed by avalanching sand on each dune--and the dark streaks indicate that wind transports sediment from the lower left toward the upper right. The picture covers an area about 3 km (1.9 mi) wide near 84.6°N, 358.5°W. Sunlight illuminates the scene from the lower left.
