Shatter cones are the only remaining visible evidence found around the Beaverhead crater's perimeter on the surface. The crater predates the Rocky Mountain orogeny, and tectonic activity has destroyed much of its morphology. Its estimated diameter is 37 miles. The crater was named for the region where shatter cones were first discovered in southwest Montana.
The evidence for impact for the Beaverhead Impact Structure resides in its shatter cones, pseudotachylites, and planar deformation features found in quartz. The age of the impact is estimated to be Neoproterozoic (600 Ma).
Shatter cones from Beaverhead make an important addition to any serious geological meteorite impact collection, as this crater is the second-known largest in the USA and the 10th largest in the world. The horsetail patterns on this shatter cone are fantastic, and they serve to make it a one-of-a-kind specimen.
