Mars "Ups and Downs"...

To complement the MOLA Laser Altimeter Mercator maps of Mars' elevations and topography, the MOLA Team also produced views of selected hemispheres.

These views emphasize specific interesting areas or angles. These maps show altitude data coded into colors - blue is low and red/white are high.
These two hemispheres are centered on the Tharsis Plateau (including the Valles Marineris and the large volcanos) and on the Isidis Impact Basin (with the Hellas Basin to the South).
