<<I heard a talk by Hoffman at an AGU meeting regarding CO2 flows, and he was ignored. �Continental drift was ignored from about 1915 to 1970 even though convincing measurements were made as early as 1912.
Hoffman's general approach on CO2 flows is described at http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2002AGUFM.P51B0354H&db_key=AST&high=4061e3e63a18001>> This paper speaks of catastrophic outflows that can produce sudden torrents of supercritical CO2 that could, under just the right circumstances, produce the braided and cut channels we see on Mars. I seen nothing whatsoever that suggests pools of liquid CO2 could have existed long enough to produced layer bedrock, salt deposits et al.
