"Bed 14," a distinctive fossiliferous unit, is exposed here thanks to the effort of one of the local landowners. In a month or two, this entire outcrop will be permanently covered with "hard stabilization" intended to stymie cliff retreat.
The outcrop features shelly skeletal material and whale bone, charcoal, and several varieties of trace fossils.
