Elysium Mons
Elysium Mons is a volcano in the Elysium Volcanic Region. It has a roughly circular caldera with deep channels running down the sides. It was discovered by Mariner 9. "Elysium" refers to a place of reward (Heaven), according to Homer in the Odyssey.[1] [2]
The smaller volcanoes Hecates Tholus (to the northeast) and Albor Tholus (to the southeast) are relatively close.
