Clustered streamlined forms in Athabasca Valles, Mars : evidence for sediment deposition during floodwater ponding

Authors(s) and Affiliation(s)



A unique clustering of layered streamlined forms in Athabasca Valles is hypothesized to reflect a significant hydraulic event. The forms, interpreted as sedimentary, are attributed to extensive sediment deposition during ponding and then streamlining of this sediment behind flow obstacles during ponded water outflow. These streamlined forms are analogous to those found in depositional basins and other loci of ponding in terrestrial catastrophic flood landscapes. Likewise, the streamlined forms in Athabasca Valley may provide the best opportunity to reconstruct the recent geologic history of the young Martian outflow channel
