| Summary: | Unusual ridges with sinuous, dendritic, and braided morphologies near the south pole of Mars as well as in the Argyre basin have recently begun to receive attention. These ridges were originally thought to be glacially formed eskers, and recent work continues to argue for this hypothesis. Indeed, an entire glacial model was built around these ridges. A brief examination of possible ridge forming processes included an esker origin but also examined other mechanisms. Of the alternative hypotheses, an origin as linear dunes is the most reasonable. The current study focuses on evidence for this mode of origin. |
