(By Gail Williams Wertz, professor emerita of pathology) I’d moved my laboratory to the University of Virginia in early 2005, and my husband and I bought a farm along the Rappahannock, one of Virginia’s most undeveloped rivers. We converted the farm from row crops to sustainable pasture and were surprised by how often we found projectile points or fragments of worked stone when putting a shovel in the ground.  I learned that our neighboring farmers had large collections of Native American artifacts found while tilling their fields.
