This image shows a layered deposit in Galle Crater, located in the Southern cratered highlands.

The geologic history of Galle Crater is not well constrained, and it contains a variety of features that have been interpreted as fluvial, lacustrine or glacial deposits.

The deposit pictured here contains multiple unconformities (sudden or irregular changes from one deposit to another), indicating periods of erosion and non deposition.
