Do we have accurate modelling of the heat flow of hte martian crust to asses this?

No. One of the datasets that is most wanting about Mars is its crustal heat flow, both average and regional. Thermal emissions instruments (TES, infrared imagers, etc.) give a rough idea, but what I wouldn't give for a set of 20 or 30 heat flow probes scattered across Mars. I'd *almost* like that more than I'd like a seismic network.

Well I couldn't find much on either the behavoir of hydrogen peroxide at ten mbar or less, or a copy of the paper on hydrogen peroxide snow theorized to form during dust storms that I could access. I suspect that these are moot points, as the martian soil is 20% iron sulfate, which a friend in the chemistry department assures me would cause H2O2 to decompose far to quickly for it to build up in significant amounts! So to answer my own question, no its not likely the gullies on mars flow with concentrated bleach! smile.gif smile.gif
