[meteorite-list] Ice-rafted rocks on dry-lakes
It's now official. We can stop calling them sailing stones. New video shows that playa rocks are being barged across the lakebed. Apparently, wind-driven, floating sheets of ice are dragging or pushing the rocks leaving their tracks in the wet lakebed sediment. Photos in the article show tracks of rocks that make tight turns and circle back into the direction from which they had come. This shows that, in these cases, the rocks are locked into the ice-sheet. http://images.realclear.com/256104_5_.jpg Bob V.

Re: [meteorite-list] Ice-rafted rocks on dry-lakes
Hi Bob and all! When I first got into meteorites, I was shocked people were still talking about is as some kind of magical thing that hadn't been figured out! I think all this does is re-affirm what many already knew. I did not take it as anything new at all! I know of the work a few of you did about a decade ago, but ice rafting has been known for decades. Disappointed that this made it official as it's been official in my mind for years and yearsnot to mention a video I posted about a year or more ago of ice sheets that were carrying rocks slamming into the shore in heavy winds. But whatever. I would still contend wind and water, without the need for ice, can do the same thing. Anyone who has tried to walk across a moist (almost muddy) dry lake knows how slippery they become! The power water and wind has is amazing! I get a kick of the giant rock ice-rafting picture!! http://www.fvalk.com/images/Arctic/1991/Rock%20conveyor.jpg Jim On 8/29/2014 10:53 AM, Robert Verish via Meteorite-list wrote: It's now official.
