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 years....not 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!!

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.
