Amazonian-aged glacial melting recorded by a subglacial paleolake and regionally widespread eskers on Mars
The mid-to-late Amazonian period on Mars (ca. 0−1 Ga) was cold and hyperarid, with an extremely limited role of liquid water. Abundant midlatitude viscous flow features (VFFs; putative debris-covered glaciers) that formed during this time are thought to be the partially retreated remnants of larger, thicker, predominan...
