About this image

This VIS image shows part of Hephaestus Fossae. Hephaestus Fossae is a complex channel system in Utopia Planitia near Elysium Mons. It has been proposed that the channels formed by the release of melted subsurface ice during an impact event. Additionally, the nearby Elysium volcanic center created subsurface heating that may have played a part in creating Hephaestus Fossae. Hephaestus Fossae is 633km long (393 miles).
