[edit] Manson Impact Crater

Manson is located near the site of Manson crater, formed by a meteorite collision that happened 74 million years ago. The crater's existence was first discovered during an oil-drilling wildcatting expedition in the 1930's. It was eventually realized to be the biggest impact by an object from outer space to happen in North America and was theorized to have led to the extinction of the dinosaurs, or contributed to it as a fragment of the Chicxulub meteor, until tests by the U.S. Geological Survey in 1991 and 1992 proved that it was too old by 9 million years.

Not much remains due to glacial till which has filled in the crater and has made it undetectable at ground level. However due to this infilling it is one of the best preserved impact sites on Earth. [1]
