THEMIS Image of the Day, July 17, 2019. This VIS image is located in the central portion of Hephaestus Fossae. Hephaestus Fossae is a complex channel system in Utopia Planitia near Elysium Mons.
It has been proposed that the channel formed by the release of melted subsurface ice during the 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.
