			Scenes of the Casius quadrangle


	The Casius quadrangle shows many features that indicate a water-rich past and much ice currently frozen in the ground. Features that are evidence of ice in the ground are pedestal craters, channels, glaciers, concentric crater fill, ring-mold craters, scalloped terrain, and polygonal ground. This region also has some landscapes that are mysteries--like strange, but beautiful linear ridge networks.
