This VIS image shows a portion of Kasei Valles. Kasei Valles is a large channel system that drained from the Tharsis volcanic highlands to the lower elevation Chryse Plainitia. At the top of the image is a deeper section of the channel with a tear-drop shaped central island. The direction of fluid flow is identified by the shape of the island, with the narrow "tail" on the down hill end.
