Abstract

New high-resolution images of the large (>20 km wide) flood channels near the Cerberus Plains and in Marte Vallis, Mars, reveal streamlined islands, longitudinal grooving, and terracing, similar to features in the Channeled Scabland (USA). These are the youngest catastrophic flood channels on Mars, formed less than 200-500 × 106 years ago, and fluvial morphologies are preserved on scales of a few metres. Peak discharges are estimated as more than 107 m3 s-1. Our data indicate that the water originated in the region north of the Cerberus Plains, and was probably related to volcanic processes.
