Ancient Asteroid That Impacted Central Idaho Left 60 Mile Crater
The planet Earth is constantly being impacted by chunks of space debris. It's not every day however that a massive rock from the heavens leaves a 100-kilometer crater on our planet's surface, and we should be very thankful for that.
One such asteroid struck an area of the Idaho-Montana border north of present-day Arco and is known as the Beaverhead Impact site . The 62-mile crater left behind is covered by mostly trees now, but the destruction left behind can still be measured with scientific equipment.
