Cool movie of the delta. It reminded me of flying over the Copper Delta area in Alaska, you could clearly see the fan formation.

With thoughts of stagnate water in this delta region on Mars it would be my first choice of exploration for signs of micro life.
My question is, could there be any chance of some form of micro peat found there?

The word ancient sounds like the key to describing a chance of existing water on Mars. This MGS/MOC image of valleys near Olympus showing craters in the valleys should help in aging the valleys I would think. Of course we still don't know if these valleys were formed by water.
