A chance discovery in a Pennsylvania groundhog hole rewrote the story of the earliest Americans, and you can explore the site just an hour from Pittsburgh.
Why it matters: Few places in the U.S. offer a deeper connection to the past than Meadowcroft Rockshelter and Historic Village, one of the oldest sites of continuous human habitation in North America.
- The National Historic Landmark in Washington County is a natural pick for our next PA Bucket List stop.
The big picture: In 1955, farmer and local historian Albert Miller discovered flint flakes, burned bone and a flint knife in a groundhog burrow on his property.
- Nearly two decades later, archaeologist James Adovasio and a University of Pittsburgh team started excavating the site.
- They uncovered a trove of artifacts, including stone tools, pottery fragments and wooden instruments. Carbon dating showed some were more than 16,000 years old, with one artifact dating back nearly 19,000 years.
- The groundhog, dubbed "Rocky," now serves as Meadowcroft's unofficial mascot.
Friction point: Before Meadowcroft, archaeologists believed the people of the "Clovis culture" were North America's first inhabitants, arriving roughly 12,000 years ago.
- Meadowcroft challenged that theory and drew fierce criticism, but subsequent discoveries at other sites ultimately reinforced the new findings and shattered one of archaeology's core assumptions.
Zoom in: Now, you can tour Meadowcroft's prehistoric rock overhang with expert guides and an observation deck.
- Check in at the Barensfeld Center to sign up for a tour. The center houses artifacts recovered from the site — from Pleistocene hunter-gatherers to prehistoric farmers, alongside a gift shop, a shaded picnic pavilion with a wood-burning fireplace, and a library for research.
- Behind the center, living-history villages span three centuries of regional history. Try an atlatl (spear-thrower) at a recreated 16th-century Monongahela village, tour an 18th-century trading post, and watch a blacksmith at work in the 19th-century historic village.
Pro tip: Ask the guides lots of questions for fascinating tidbits. One favorite: "Buck" became slang for money in the 1700s, when deerskins were commonly used in trade.
