Geologic map of the Elysium region of Mars

The region centered at Elysium Mons contains that second largest volcanic complex on Mars, surpassed in size by only the Tharsis complex. The Elysium region also has been a center of tectonic, fluvial, and mass-wasting activity. After degradation of ancient cratered terrain within the northern lowlands, volcanic rocks erupted from Elysium Mons, Hectas Tholus, and Albor Tholus in Elysium Planitia.
