HiRISE PICTURE OF THE DAY: 3 MARCH 2026
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.
