This is a colorized topographic map of the volcanic province Elysium, together with its surroundings, from the Mars Orbiter Laser Altimeter (MOLA) instrument of the Mars Global Surveyor spacecraft. Elysium, in the eastern hemisphere of Mars, is the second largest volcanic region on the planet, after Tharsis. The largest shield volcano, Elysium Mons, is at center, while the smaller volcanoes Hecates Tholus and Albor Tholus are to the former's upper and lower right, respectively.
