Hecates Tholus is a volcano in the Elysium Volcanic Region.
Hecates is in the Cebrenia quadrangle. It is thought that the caldera may have had glaciers in the past.[1] Some valleys on Hecates show a parallel drainage pattern.[2] 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 ice still exists under a cover of debris. They state the ice could be "accessible for automated or human exploration."[3] On Earth 8 million year old ice is still present in the Antarctic dry valleys under a layer of dirt.[4]
