Gasa impact crater, Mars: Very young gullies formed from impact into latitude-dependent mantle and debris-covered glacier deposits?

► Gasa crater formed during a recent glacial epoch (2.1-0.4 Ma). ► Post-Gasa gullies are related to melting of ice-rich mantling deposits. ► Gasa crater post-dates, and therefore does not contain, mantling deposits. ► Gullies within Gasa are due to the impact occurring into debris-covered glaciers. ► Found near Gasa, debris flows due to the impact support the presence of glaciers.
