Elysium (volcanic province)

Elysium, located in the Elysium and Cebrenia quadrangles,[1] is the second largest volcanic region on Mars, after Tharsis.[note 1] The region includes the volcanoes (from north to south) Hecates Tholus, Elysium Mons and Albor Tholus. The province is centered roughly on Elysium Mons at 24.7°N 150°E / 24.7; 150. Elysium Planitia is a broad plain to the south of Elysium, centered at 3.0°N 154.7°E / 3.0; 154.7.[2] Another large volcano, Apollinaris Mons, lies south of Elysium Planitia and is not part of the province. Besides having large volcanoes, Elysium has several areas with long trenches, called fossa or fossae (plural) on Mars. They include the Cerberus Fossae, Elysium Fossae, Galaxias Fossae, Hephaestus Fossae, Hyblaeus Fossae, Stygis Fossae and Zephyrus Fossae.

Volcanoes of Elysium

Troughs (fossae) in Elysium
  • Troughs to the east of Albor Tholus, as seen by HiRISE under the HiWish program
  • Portion of a trough (fossa) in Elysium, as seen by HiRISE under the HiWish program (blue indicates probably seasonal frost)
  • A Cerberus Fossae trough, as seen from THEMIS
  • Wind-blown material darkens areas around a Cerberus Fossae trough (scale bar for HiRISE image is 500 m)
  • The Cerberus Fossae, as seen by HiRISE (scale bar is 1.0 km)
  • The Elysium Fossae, as seen by HiRISE (click on image to see layers)
  • Two views of the Hephaestus Fossae, as seen by HiRISE (picture on right lies to the top (north) of other picture). Fossae often form by material moving into an underground void.
