Flowing Carbon Dioxide Glaciers on Mars

Carbon dioxide glaciers on Mars are found to be still flowing today, moving 100 times faster than water ice under Martian conditions when on a slope.

IMAGE: Perspective view of the South Polar Cap of Mars using Viking imagery draped over topography from the Mars Orbiter Laser Altimeter. White ice is residual carbon dioxide cap that resides on top of and protects the much thicker CO2 glaciers. The surrounding terrain is composed of red dust that overlies the mountains in the background and the 4 kilometer thick H2O ice cap that supports the CO2 glaciers.
