Where: York County, Virginia (37.2° N, 76.5° W: paleocoordinates 37.3° N, 75.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Moore House Member (Yorktown Formation), Late/Upper Pliocene (3.6 - 2.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Moore House Mbr of the Yorktown Fm, which unconformably overlies regionally the Morgarts Beach and Rushmere Mbrs of the Yorkown Fm, and is unconformably overlain regionally by the Chowan River Fm.
