It's hoarfrost so there has to be sublimation of water then the water vapor needs a sub-freezing surface to crystalize on. There wouldn't be any wind in those gaps between the rocks. It was just so unusual to see the frost on the vertical surfaces but none on the top surface of anything, it was only between the rocks and only in specific locations. Whatever the conditions which led to its formation like that it was pretty cool to see. -- Brian --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "StrataList-OT" group.
