Claritas Fossae Channels and Delta

Today's VIS image shows two unnamed channels on the western edge of Claritas Fossae. The small channel joins the larger one close the the crater rim. The main channel has formed a delta in the crater. Deltas are formed when sediment laden rivers slow down - either due to a flattening of topography, or entering a standing body of water. The reduction in velocity causes the sediments to be deposited. The main channel often diverges into numerous smaller channel that spread apart to form the typical fan shape of a delta.
