Eberswalde Crater contains layered rocks about 100-meters thick exposed in a well-preserved delta.

This sedimentary deposit contains dozens of shallowly tilted, alternating bright and dark layers of varying thickness (one to 10 meters). HiRISE terrain models reveal structures in these layers which are interpreted as lake-floor deposits.

This delta is distinguished from other fan-shaped deposits on Mars by the presence of a preserved distributary network including lobes, inverted channels, and meander cutoffs. Another example of a fan with a distributary network can be found in Jezero Crater, which may represent a more degraded version of the same kind of system, and where the Mars 2020 rover will be exploring.
