This channelized area is near the source region of the huge outflow channel, Ares Vallis. It was at the distal end or “long-ways down-river-area” where the Pathfinder/Sojourner mission landed on 4 July 1997.
This tiny region of Ares Vallis is on a plateau and did not contribute much to the overall water discharge. The slope downhill at the northeast edge of the image leads to the main channel.
Dune- and ripple-like formations called “transverse aeolian ridges” have since covered the bottom of the channels. These are oriented perpendicularly to the winds that must flow through these now-dry channels.
