A habitable environment on Martian volcano?

Possibly habitable environs

Heat from a volcano erupting beneath an immense glacier would have created large lakes of liquid water on Mars in the relatively recent past. And where there’s water, there is also the possibility of life. A recent paper by Brown University researchers calculates how much water may have been present near the Arsia Mons volcano and how long it may have remained.
