Martian channels linked to dry ice

The seemingly common occurrence of flood channels on Mars can be traced to the sudden melting of buried deposits of frozen carbon dioxide, according to a theory advanced by Daniel J. Milton of the U.S. Geological Survey in Menlo Park, California, who points to the Washington scablands and the frozen natural gas fields of Siberia for support.

Milton, a member of a team of USGS scientists that is studying and mapping the surface and structure of Mars, says that the channels ‘appear to have been shaped by sudden discharges of water that dwarf the flow of the Amazon.’
