Coloe Fossae Region (3-D)

The Coloe Fossae region is a series of enclosed, intersecting canyons. The floors of the canyons in this image contain complex set of ridges and grooves that are generally parallel to the canyon walls and look like they have undergone flow, called lineated valley fill. It is probably made of ice-rich material and boulders that are left behind when the ice sublimates.
