Description: Locality: U.S. Western Interior Seaway The W.I.S. Impact Crater. I got lucky tracing all of my impact-related materials to a crater structure that EXACTLY matches the crater morphology of the infamous Chicxulub Impact Structure (66mya) pictured below. Note: All 3 of these structures were likely under water at the time of impact.
