The Phlegra Dorsa region consists of ancient hills that have been surrounded and partially buried by flows from the Cerberus Fossae to the south. These flows could have been mud-laden water floods or very large lava flows.
The margin visible here is similar to that on lava flows that have had a long history of liquid lava being injected underneath the solidified crust. Relatively fresh impact craters and recent dust devil tracks are also visible.
