About this image

The channel-like features in this VIS image are tectonic graben. These graben are called Sirenum Fossae. Graben are created in regions of extensional tectonic stress, where the bedrock is faulted and pulled apart, allowing linear sections of the surface to drop downward along paired faults. The Sirenum Fossae graben are 2735km (1700 miles) long.
