THEMIS Image of the Day, July 3, 2018. This VIS image is located in Terra Sabaea near the margin of Syrtis Major Planum. The channel-like feature in the bottom of the image is an unnamed feature.
There is a high spot within the channel that would not let a fluid pass from one side to the other. This indicates that this is not a water carved channel, but was most likely an underground lava tube, where collapse of the roof has revealed the underlying feature.
The 90 degree turns in the channel feature, and the small linear ridges just to the top of the channel indicate tectonic forces are part of the processes at work in this region.
