Faulted Layers in Collapse Pits
ESP_044497_1730  Science Theme: Geologic Contacts/Stratigraphy
This image shows a set of coalesced collapse pits in western Valles Marineris.

Fine layers are exposed in the walls of the pits, and in some places those layers are displaced by faults. What formed these layers, and what caused them to collapse into pits? Detailed study of this image and other data should help answer those questions.
