Color coding indicates the topography in this map of the region of Mars from 65 to 72 degrees north latitude and from 230 to 250 degrees east longitude. This area was designated "Region D" in the process of evaluating potential landing sites for NASA's Phoenix Mars Lander. The location chosen for safe landing sites is within the box bordered with a heavy black line along the western boundary of this region.
Elevation in the region varies from about 3,600 meters (11,800 feet) to 4,400 meters (14,400 feet) below the zero reference point for Martian surface elevation. The topographical information is from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor orbiter.
