The Story
This marker records a rare official gesture: Pennsylvania's naming of Meadowcroft Rockshelter a "Commonwealth Treasure." The designation set the deeply stratified site apart as a public trust, calling on citizens to protect and preserve a place that holds evidence of the state's — and the continent's — earliest human history. It reflects how a working farm's chance discovery became recognized as belonging to everyone.
Why it matters
It shows a modern society deliberately choosing to safeguard the material record of its most ancient inhabitants, elevating an archaeological site to the status of shared heritage.

Meadowcroft Rockshelter
Jefferson Township, PA · est. 1999
Beneath a sandstone overhang in the hills of Washington County lies one of the most important archaeological sites in the Americas. When farmer Albert Miller reported artifacts here in 1973, University of Pittsburgh archaeologists began peeling back layers of deposits that reach back nearly 16,000 years — pushing the story of human presence in North America deeper than almost anywhere else on the continent. Its stratified record preserves an unbroken sequence of the peoples who hunted, camped, and lived in this valley across the millennia.
Doddridge's Fort
Independence Township, PA · est. 1947
Around 1773 John Doddridge raised a cluster of stockaded cabins on this frontier, strong enough to shelter neighboring families when danger threatened. Through the Revolutionary years such fortified homesteads were the settlers' refuge from raids along the western border. The place is also remembered as the boyhood home of Dr. Joseph Doddridge, later a noted chronicler of frontier life.
Miller's Blockhouse
Donegal Township, PA · est. 1947
Jacob Miller built his blockhouse around 1780 as a gathering point and refuge for the scattered settlers of the Dutch Fork country. On March 31, 1782, in the closing months of the Revolution's frontier warfare, the post came under attack, and Ann Hupp rallied its defenders in a heroic stand that entered local legend. Such fortified strongpoints were the difference between survival and abandonment on this exposed border.
Washington
North Franklin Township, PA · est. 1947
Founded in 1781 by John and William Hoge on the site of the Native Catfish Camp, Washington grew from a frontier plat into a borough (1810) and later a city (1923). Its fortunes were tied to the National Road, the federally built highway that funneled settlers and commerce westward through southwestern Pennsylvania. Named for George Washington, the town became rich in historic buildings and associations as traffic streamed past its doors.
