Re: [asa] AIG blurb on fossilization

This is a red calcareous conglomerate of Pleistocene age on the north side
of Hot Springs. There were low cliffs - 6ft and it was used as a building
stone. We couldn't stop so I never had a proper look.

Jeff Greenberg said what it was and it is in roadside geol for SD

It was the same colour as the Swordfish formation (Triassic?)which has to be
collected in plastic bags as it is so friable.
