If that thing makes it there it may detect mineralogical evidence inconsistent with magmatic processes and consistent with CO2 solution.

The THEMIS aboard 2001 Mars Odyssey should be able to return high-resolution spectra of Isidis that could nail down whether or not the flows derive from volcanic processes, though Beagle 2 should be able to bore under any surficial mantle that may mask spectra from orbital detection. At any rate, your LPSC abstract notwithstanding, I take it that you do not dispute the Lanagan et al. interpretation for the phreatic cones in Cerberus plains, Marte Valles, and Amazonis Planitia? Or do you believe in a similar (CO2-related) flow mechanism, rather than volcanism, for these areas as well?
