THEMIS image: Into the crater

THEMIS Image of the Day, February 28, 2014. Several channels are located on the flank of Hecates Tholus. In this VIS image one of those channels enters a crater, creating a deposit on the floor of the crater. Age relationships can be derived from this image. Hecates Tholus was formed first, then the crater was created, and finally flow of lava or water carved the channel that bisects the crater rim. More THEMIS Images of the Day by geological topic.
