This real Beaverhead Shattercone is museum grade.
Dubbed "Angelwings" it is our huge, 73 pound, museum-grade shatter cone from the Beaverhead, Montana
asteroid impact site. It's shown here in approximately correct scale with our handyman Atlas.
As with every shatter cone, Angelwings is a beautiful and fascinating relic of a devastating day
(estimated at 600 million years ago) in what is now Montana, USA. On that day an asteroid estimated
to have been about 6 miles in diameter slammed into the Earth, creating a maelstrom of shock,
heat, and fiery shrapnel that would have destroyed the animal life and vegetation in a circle
encompassing most of the present-day United States. The remains of the 35 mile diameter crater
lie in SW Montana and Idaho, and this beautiful red quartzite shatter cone is a witness to the
Shattercones are among the most interesting geological rocks on Earth.
