"Sailing Stones" in Death Valley

stonesatiety

LRichard: The keel is the rock itself protruding beneath the ice.

I would like to see it done with a 700 pound stone. Could freezing and melting water volume changes lift it far enough? I suppose the rapid temperature changes could account for liquid underlying the ice. If ground temperature melts the ice, it should be soft enough to allow the stone passage. Maybe somebody needs to place wildlife observation cameras around the playa?

Or maybe the alien death ray can be set to melt only a layer of ice? Of course, if we want to see the aliens, the best way is to order pizza and mark it with an infrared strobe. In case they are concealing themselves within Occam's Razor.

The floating rock theory so full of contingencies that it can almost be sunk by Occam's razor in favor of some sort of alien trickery. })
