Guests	Scanning through the LPSC Mars abstracts, the thing that struck me the hardest was that the Gully Wars are still on full-tilt. There are at least four totally different rival theories presented -- plus Allen Treiman's insistence, for the second year in a row, that the evidence points against ALL of them in at least some cases, raising the possibility that they're being made by different causes in different places. Subsurface aquifers: http://www.lpi.usra.edu/meetings/lpsc2006/pdf/1666.pdf http://www.lpi.usra.edu/meetings/lpsc2006/pdf/2049.pdf http://www.lpi.usra.edu/meetings/lpsc2006/pdf/2412.pdf Melting surface snow: http://www.lpi.usra.edu/meetings/lpsc2006/pdf/1610.pdf AGAINST melting surface snow: http://www.lpi.usra.edu/meetings/lpsc2006/pdf/1201.pdf Dust landslides: http://www.lpi.usra.edu/meetings/lpsc2006/pdf/1345.pdf CO2 snow landslides: http://www.lpi.usra.edu/meetings/lpsc2006/pdf/1646.pdf None Of The Above: http://www.lpi.usra.edu/meetings/lpsc2006/pdf/1304.pdf But this, I think, is one mystery that will probably be settled by MRO, given its combination of very high-resolution surface photos, mapping of shallow subsurface aquifers, and extremely detailed near-IR mineral maps.
