A Cliff of Ice in Malea Patera
ESP_082999_1165 Science Theme: Geologic Contacts/Stratigraphy

Malea Patera is one of four volcanic constructs that make up Malea Planum in the Southern Highlands of Mars. This image shows the southern-most part of Malea Patera’s plateau escarpment.

On these steep scarps, ice can still be seen on the south facing walls of the scarp towards the end of the Southern Hemisphere’s winter.
