Geologist: Ice may hold clues to life on Mars Reuters

Giant ice towers that formed next to steaming volcanic vents in the freezing atmosphere of Mars may be the best place to look for life on the red planet, an Australian geologist said on Monday. Nick Hoffman of the University of Melbourne said the latest images taken by the Mars Odyssey orbiter had revealed curious hotspots in the Hellas Basin that could be similar to ice towers in Antarctica, where microbial life forms live on chemical energy.
