Hi Ross - I guess you missed the show:
http://www.youtube.com/watch?v=f1GCgOI3B1o The black impactite layer is pretty amazing - I never expected it to be that dense or clearly obvious to the naked eye - my guess is that it extends throughout other sandstone formations in the region - The only KT impactite samples that I have seen were at the Smithsonian, and came from the deep sea bed. But we've all seen the impactite layers from Italy that the Alvarez's sampled. I don't know of any exposed Chesapeake Bay impactite layers, but... good hunting, E.P.
