Utopia Planitia is located at the mouth of
outflow channels and exhibits various geological units (eolian, fluvial
volcanic materials). Northern lowland plains; includes subpolar plains of
Vastitas Borealis, plus mottled terrain interpreted to be wind-deflated,
and grooved terrain (periglacially modified?) of Hesperian age; also
includes part of the Elysium formation (lava flows and/or lahars from the
Elysium volcanics). In these northern plains, a concentration of rampart
craters involves the presence of a continuous and a near-surface
ground-ice. The Landing Site Of Viking II. |
