This unnamed crater in Arabia Terra appears to be the source of the channel that runs to the top of the frame. This channel/crater combination is part of a much larger channel system in Arabia Terra. The linear striations in the channel and the deposits on the crater floor are indicative of glacier flows in the distant past. The striations are medial moraines in active glaciers, marking where sediment was carried by flowing ice. Now the ice is gone, but the sediment remains.

Image information: VIS instrument. Latitude 40.5N, Longitude 11.7E. 19 meter/pixel resolution.

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.
