Mars Odyssey THEMIS Image: Chasma Boreal Dunes
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.

Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.
