Gullies in Acidalia Planitia

This observation covers gullies that were previously identified in the walls of a crater in a MOC image (E0502675).

Do these gullies have features that can be interpreted as characteristic of snow and/or ice melting? At HiRISE resolution, questions like this can possibly be answered.

HiRISE often re-images areas to track seasonal changes, so we expect to monitor these gullies for changes at intervals during several Mars years.

Note: These gullies are in a crater in Acidalia Planitia, to the northeast of Gamboa Crater.
