Mars Orbital Recon: The Upstream Edge Of A Crater in Athabasca Valles

This observation should provide us a closer look at lava-topography interactions in this area.

Athabasca Valles is a young outflow channel system on Mars that may have been carved by catastrophic water floods.

Other HiRISE images reveal that Athabasca Valles is now entirely draped by a thin layer of solidified lava, the remnant of a once-swollen river of molten rock.
