wind erosion?
yes it may be effective but not on Mars. The erosion rate on Mars is less than 75 mm every million years at most and typically less than a tenth of this figure. So much for the ability of wind erosion on Mars.... Good theory though...pity about the wind..or lack of it.

Please forgive me if I misread your post, but just to be clear - Hynek and Phillips specifically rule out aeolian processes to account for the denudation, though wind action certainly would be a (minor) contributing factor over time.
