HiPOD 1 June 2022: Depressions near Coogoon Valles

This feature likely formed by collapse. Its origin is unknown, but it fits the bill of a candidate caldera formed through ancient explosive eruptions near the dichotomy boundary. This region is characterized by a thinner crust compared to the rest of the highlands and by the occurrence of massive clay-bearing materials.
