HiPOD Tuesday, 12 Oct 2021: The Writing is on the Wall
These U-shaped ridges along this crater’s interior wall provide clues to an ice-rich past. The curved, scalloped ridges, called moraines, are made up of rocks that the glacier collected as it moved downslope.

Looks more like the wall settled down to the right and stressed the upper walls to create those lines/cracks.
@HiRISE What might be a time period for these Glaciers moving down the inside of the crater? Centuries or …?
