Context image

The pits in this VIS image are collapse features on the northern flank of Ascraeus Mons. Such collapse pits, often forming a linear pattern, are thought to be related to lava tubes below the surface that have been emptied of the final flow and forming a void. When the weight of the roof over the void overcomes the strength of the walls gravity caused the roof to collapse.
