Impact Crater amid the Deuteronilus Mensae

This crater with spectacular ejecta is located in the northern mid-latitudes in the Deuteronilus Mensae, located near the dichotomy boundary, where the southern highlands transition into the northern lowlands.

The crater has raised, fluidized ejecta. Scientists think that fluidized ejecta forms when an impact occurs into ice-rich material. The interior of the crater shows some material, particularly on the west wall, that has detached and is flowing into the crater center. This suggests the presence of ground ice.
