I don't believe it. The depth of the impression left behind suggests the rock is far too heavy to have been pushed by wind.
Reminds me of the unexplained spirals and lines all over the dry lakebed of Vernuekpan in South Africa:
I do love a good mystery!
Its swamp gas!
I also am a skeptic of the ice theory.
Well, it’s not the rock itself that’s pushed by the wind but broken up sheets of ice. The flat ice pieces push the rocks along, or the rocks are embedded in them and scrape along the ground as the ice pieces are blown along. In other words the ice pieces sort of act like sails for the rocks.
Something else to keep in mind is that when this happens the ground is probably wet, not dry as in the pic. I know from experience that the ground out there turns into a slippery mud when it’s wet. This would act to lubricate the path that the rock moves along. Their theory seems plausible to me.
-do love a good mystery!
The problem with a good mystery is that when it’s solved it’s no longer a good mystery.
