The wind-sculpted yardangs in this scene are part of the Medusae Fossae Formation, a regionally extensive geologic unit that probably was produced from the accumulation of volcanic ash. The yardangs occur at multiple scales and orientations, perhaps an indication of variations in wind direction and magnitude that could be the result of climate change.
