Eroded Crater Deposit in the Eastern Arabia Region

This image shows a hill which has eroded into a structure of pits and troughs . One possible cause of this type of degradation could be loss of ice from the surface material.

Similar textures are seen in several nearby craters as well as in other regions of the planet.
