This image superimposes Gamma-Ray Spectrometer data from NASA's Mars
Odyssey orbiter onto topographic data from the laser altimeter on NASA's
Mars Global Surveyor. The red arrow indicates the shield volcanoes of
Elysium rise in northern Mars, seen obliquely to the southeast.
Blue-to-violet colors at the Elysium rise and highlands stretching to the
foreground of the map mark areas poor in potassium. Red-to-yellow colors
mark potassium-rich sedimentary deposits in lowlands below the 1997 Mars
Pathfinder landing site (PF) and 1976 Viking 1 landing site (V1).
