hi Nick -

It's bizarre how regularity of volatile releases by massive impact events on Mars is somehow now being ignored. The stratigraphy on Mars is clearly shown in the images, but no work on counts seems to be being done. If these massive impacts are occuring roughly (chaotically) every 26 million years, then sa simple count and multiplication should give some very rough surface age minimums - as sometimes Mars would not get hit, all that would be shown would be a minimum, not a the maxima, but at least one would have that...

Also, for smaller (say multi-kiloton) recent impacts, the differences between the effects of the CO2 and water released from the clathrates seems to be being overlooked, as well as the secondary releases the initial release causes. You look at the gullies running out from a small crater, you see the water - what damn little of it there is.
