A Pedestal Crater in Malea Planum
A Pedestal Crater in Malea Planum
ESP_022787_1085  Science Theme: Impact Processes
As the name suggests, pedestal craters usually have ejecta (material thrown out from impact) that is above the surrounding terrain. In some cases, the material can be more erosion-resistant. Some suggest that these units were once rich in volatiles (e.g., water ice).

This specific pedestal in Malea Planum is one of the largest on Mars, and fine layering is visible along its margins.

This caption is based on the original science rationale.
