Regional outcrops of unconsolidated Miocene Yorktown Formation sands. Diverse and abundant Upper Miocene invertebrates. A few vertebrates -- mostly shark teeth -- as well.
The most accessible outcrops are near the South bank of the York River from Williamsburg to and including Yorktown in roadcuts, stream cuts, and any other exposures. Unlike the older Miocene formations along the Calvert Cliffs where collecting is almost entirely restricted to beaches where most shells are fragmented., invertebrates are commonly weathered out and intact.
Much of the area is US government park land. Collecting is probably technically illegal or restricted, but may be tacitly permitted in road cuts and such if done judiciously. Collecting on private land requires property owner permission as it does everywhere.
Yorktown exposures are common along the rivers feeding into the South part of Chesapeake Bay from Virginia Beach West to Petersburg.
