Meadowcroft Rockshelter

Washington County · dedicated 1999 · 401 Meadowcroft Rd.

A deeply stratified archaeological site, its deposits span nearly 16,000 years. Discovered in 1973 by Albert Miller and excavated by University of Pittsburgh archaeologists. Meadowcroft revealed North America's earliest known evidence of human presence and the New World's longest sequence of human occupation. All of eastern North America's major cultural stages appear in its remarkably complete archaeological record.
