Snowhenge is, or was, an artefact built in January 1992 at S80° 06´, W41° 53´, on the Filchner Ice Shelf, Antarctica. It’s architects were myself, Dr Jeff Ridley, and Peter Webb. It doesn’t have a deep and meaningful reason, but it goes to show that there isn’t much on TV in Antarctica. It was used in an experimental effort to invoke Druidic powers to refill a sadly depleted bottle of Bushmill’s best Irish Whiskey, but this ended in tragic failure.
As far as I can tell, ours was the first and original Snowhenge. But more than a few other Great Minds have thought alike. Nancy Wisser has dedicated the Clonehenge blog to Stonehenge replicas, and you can find plenty of the icier variety there.
