Greenwood Furnace

Pennsylvania invented the American company town — coal patches and oil booms that burned bright and short.

Greenwood Furnace State Park is a 423-acre (171 ha) Pennsylvania state park in Jackson Township, Huntingdon County, Pennsylvania, in the United States. The park is near the historic iron making center of Greenwood Furnace. The park includes the ghost town of Greenwood that grew up around the ironworks, old roads and charcoal hearths. Greenwood Furnace State Park is adjacent to Rothrock State Forest and on the western edge of an area of Central Pennsylvania known as the Seven Mountains. The park is on Pennsylvania Route 305, 20 miles (32 km) south of State College.

The on-the-ground condition of Greenwood Furnace is unverified — it's listed here with unknown status. That could mean standing buildings, or an empty field. Go prepared for either, and consider sharing what you find so the record improves.

Nobody has confirmed the access situation, so treat any visit as reconnaissance: verify land ownership first, and be ready to admire from the road.

Ghost-town etiquette is simple: take only photographs. Removing artifacts is illegal on public lands and disrespectful everywhere else — and on federal land it can be a serious offense.
