Signs of Glaciers
During the past, the region experienced extensive glaciation and is therefore characterized by landforms that resulted from multiple glacial epochs. All of the low lying terrain is covered by smooth deposits, partly showing flow patterns that indicate slow downhill movement of the material. The viscous flow features surrounding the plateaus resemble rock glaciers and debris-covered glaciers found in cold-climate areas on Earth, and most likely consist of ice mixed with mass-wasted debris.
