Template:Short description Template:Infobox terrestrial impact site The Beaverhead impact structure is the second-largest impact structure within the U.S. It lies within the states of Idaho and Montana. Estimated at Script error: No such module "convert". in diameter, it is among the largest impact structures on Earth.
With an estimated age of 600 million years (Neoproterozoic), the impact's original shatter cones along the impact structure's perimeter provide some of the structure's only remaining visible evidence.
