This real Beaverhead Shattercone is 4 ounces
Collectors -grade shatter cone from the Beaverhead, Montana asteroid impact site.
As with every shatter cone, they are fascinating relics 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 90 mile diameter crater lie in SW Montana and Idaho, and this beautiful red quartzite shatter cone is a witness to the destruction.
Shattercones are among the most interesting geological rocks on Earth.
