Rich Barclay in an outcrop named "Big Phone Booth".  Bottom of outcrop is carbonaceous mudstone, above that is coal (lignite), then a white ash layer, then Paleocene plants.  Thus, the K-T boundary has been crossed in this single outcrop.  Evidence of K-T is present in pollen, shocked quartz, Iridium and a 50% extinction rate of plants.
