Chasma Boreal Dunes
About this image
The large sand sheets and dunes observed in this THEMIS image are located near the north pole of Mars. Changes in surface albedo across the image are likely due to variable thicknesses of dark sand that cover lighter surfaces. Layering of units is observed near the top of the image and is evidence to changing conditions throughout the geologic history of Mars.
