In this HiRISE image, there are two different shapes of the channels. One channel, shown from the lower left to the upper right, is filled in with the same materials around it. The other channel, shown in the lower right, is darker and depressed in topography.

From these different morphologies, we are able to determine that the filled in channel is older while the depressed channel is younger, indicating at least two different times when water flowed in this region.
