Albor Tholus is an extinct volcano in the Elysium Planitia area on Mars. It lies south of the neighbouring volcanoes Elysium Mons and Hecates Tholus. Albor Tholus is 4.5 kilometres[1] high and has a diameter of 160 km[1] at its base. Its caldera has a diameter of 30 km and is 3 km deep.[1] Compared with terrestrial volcanoes the caldera is unusually deep. Evaluations by the Mars probe Mars Express found that the volcanoes of the Elysium region were active over long periods.
