Hecates Tholus is a volcano in the Elysium Volcanic Region.

Tographic map of area around Hecates Tholus

Hecates is in the Cebrenia quadrangle. The volcano is at location 32.12°N 150.24°E, in the volcanic province Elysium, and has a diameter of 182 km. It is the northernmost of the Elysium volcanoes; the others are Elysium Mons and Albor Tholus. Hecates Tholus is in the Cebrenia quadrangle.

Origin of name

In planetary nomenclature, a "tholus" is a "small domical mountain or hill". Hecates is named after Hecate, the goddess of the ghost-world, nightly events, and sorcery.[1]

It is thought that the caldera may have had glaciers in the past.[2]  Some valleys on Hecates show a parallel drainage pattern.[3]  Using the High Resolution Stereo Camera onboard ESA's Mars Express that is orbiting Mars, a team of researchers discovered evidence of a large explosive eruption and recent glaciers on the volcano.  Although some of the ice has sublimated into the atmosphere, the authors believe there still exists ice under a cover of debris.  They state the ice could be "accessible for automated or human exploration."[4]  On Earth 8 million year old ice is still present in the Antarctic dry valleys under a layer of dirt.[5]
