Hephaestus Fossae

This VIS image is located in Utopia Planitia and shows part of Hephaestus Fossae. Hephaestus Fossae is a complex channel system. It has been proposed that the channel formed by the release of melted subsurface ice during an impact event that created a large crater south of this image. Additionally, the nearby Elysium volcanic center created subsurface heating that may have played a part in creating both Hephaestus Fossae and Hebrus Valles to the north.
