Hephaestus Fossae

This VIS image is located in the northern portion 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 the impact event that created a large crater southeast 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. The right angle intersections indicate there is some tectonic activity in the region, and the circular depressions indicate surface collapse into subsurface voids. Hephaestus Fossae is a very complex set of features.
