Terra Sabaea Channels

Today's VIS image shows part of the northeastern margin of Terra Sabaea. This regional boundary between the highlands of Terra Sabaea and lowlands of Utopia Planitia is heavily dissected by both fluid flow channels and extensive faulting. While many of the channels are unnamed, this image has three named channels: Clasia Vallis (center of image with ridge in the middle of the channel), Hypsas Vallis (the next channel below Clasia Vallis) and Clanis Valles (the very shallow channel at the bottom of the image). Clasia Vallis is 147km (91 miles) long, Hypsas Vallis is 33km (20 miles) long. and Clanis Valles is 58km (36 miles) long.
