It lies south of the neighbouring volcanoes [Elysium Mons](/source/Elysium_Mons) and [Hecates Tholus](/source/Hecates_Tholus). Albor Tholus is 4.5 kilometres[2] high and has a diameter of 160 km[2] at its base. Its large [caldera](/source/Caldera), having a diameter of 30 km and a depth of 3 km,[2] is deep compared to calderas on the Earth. The elevation of the lowest level of the caldera is the same as the base of the volcano; however, the original lower slopes of Albor Tholus may have been covered by lava flows from its larger neighbor, Elysium Mons. Evaluations by the Mars probe [Mars Express](/source/Mars_Express) found that the volcanoes of the Elysium region were active over long periods. - Topography of Albor Tholus and its neighborhood. - Albor Tholus as seen by THEMIS. The area has undergone extensive faulting. ## References 1. **[^](#cite_ref-1)** ["Albor Tholus"](https://planetarynames.wr.usgs.gov/Feature/166). *Gazetteer of Planetary Nomenclature*.
