We propose that gullies <br />form on slopes with geometries (elevation, slope, azimuth) <br />that result in a specific temperature pressure <br />environment (not too hot and not too cold) conducive <br />to both the preservation and melting of ice in the uppermost <br />subsurface." <br />http://www.lpi.usra.edu/meetings/7thmars2007/pdf/3320.pdf <br /><</safety_wrapper> <div class="Discussion_UserSignature"> </div>

Dr. Fomitchev's full submitted journal article is available on his website:<br /><br />Transient Melt Water Ponding in Central Aram Chaos on Mars.<br />http://www.cse.psu.edu/~mif10/AramChaosWater.doc [12.5 mbytes]<br /><br />From the article:<br /><br />"Ground ice<br />As one can see from Table 1 Amazonis, Arabia, Aram Chaos, Elysium and Hellas basin areas allow a maximum of 3.5 hours per day for liquid water to persist on the surface with between 50 and 275 days per Martian year when the transient water conditions are met. It should be emphasized that within the highlighted areas the most likely spots for transient liquid water to occur would be craters and depressions where higher surface pressure provides more stable conditions and the subsurface ground ice is present."<br /><br />Bob Clark <br /><br /> <div class="Discussion_UserSignature"> </div>
