Noachis Terra (lit. "Land of Noah") is an extensive southern landmass (terra) of the planet Mars. It lies west of the giant Hellas impact basin, roughly between the latitudes −20° and −80° and longitudes 30° west and 30° east, centered on 45°S 350°E / 45°S 350°E / -45; 350Coordinates: 45°S 350°E / 45°S 350°E / -45; 350. It is in the Noachis quadrangle.

The term "Noachian epoch" is derived from this region.



Gullies on DunesEdit

Gullies are found on some dunes. These are somewhat different than gullies in other places, like the walls of craters. Gullies on dunes seem to keep the same width for a long distance and often just end with a pit, instead of an apron. Many of these gullies are found on dunes in Russell (Martian crater).

Coloring of the base map indicates relative elevations, based on data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor. Whites and browns indicate the highest elevations (+12 to +8 km); followed by pinks and reds (+8 to +3 km); yellow is 0 km; greens and blues are lower elevations (down to −8 km). Axes are latitude and longitude; Poles are not shown.
