[4] Another large volcano, Apollinaris Mons, lies south of Elysium Planitia and is not part of the province.

[7] It has been hard to study the composition of this province, due to the layer of dust that sits on top of the crust.

[9] There are some extant near-surface glacial deposits in the caldera of Hecates Tholus, a volcano in the province.

[6] The southeastern portion overlaps with Cerberus Fossae; features in this region are thought to have formed due to volcanic and water-related processes, such as phreatomagmatism, relict ice flows, and interactions between lava and water.

[3] Elysium contains numerous lava flow units with variable histories as well as volcanic and fluvial channels.

[16] The Elysium volcanic province was first noticed as a distinct Martian region as a result of data obtained from the Mariner 9 mission, in the 1970s.

[22][10] The InSight Lander landed just south of the province in 2018,[9] in Elysium Planitia, and has detected marsquakes emanating from this region.
