Hellas Quadrangle - Glacial Features

Glacial Features

• Surface features that show down hill movement, as seen by HiRISE.

• CTX context image of Hellas Planitia showing location of next two images.

• Surface in Hellas quadrangle, as seen by HiRISE, under the HiWish program.

• Possible Glacial Cirque in Hellas Planitia, as seen by HiRISE, under the HiWish program. Lines are probably due to downhill movement.

• Context for the next image of the end of a flow feature or glacier. Location is Hellas quadrangle.

• Close-up of the area in the box in the previous image. This may be called by some the terminal moraine of a glacier. For scale, the box shows the approximate size of a football field. Image taken with HiRISE under the HiWish program. Location is Hellas quadrangle.

• Material Flowing through a crater rim, as seen by HiRISE, under the HiWish program. Lateral moraines are labeled.

• Glaciers, as seen by HiRISE, under HiWish program. Glacier on left is thin because it has lost much of its ice. Glacier on the right, on the other hand, is thick; it still contains a lot of ice that is under a thin layer of dirt and rock.

• Tongue-shaped glacier, as seen by HiRISE under the HiWish program. Ice may exist in the glacier, even today, beneath an insulating layer of dirt.

• Close-up of tongue-shaped glacier, as seen by HiRISE under the HiWish program. Resolution is about 1 meter, so one can see objects a few meters across in this image. Ice may exist in the glacier, even today, beneath an insulating layer of dirt.
