About this image

Valley networks are a relatively common feature in the southern highlands of Mars. This THEMIS visible image contains several of these small channels. Some appear clustered near the smaller crater at the top of the image. There is still some debate over the origin of these enigmatic martian landforms. Were they caused by overland flow after precipitation, underground sapping, or a combination of both?
