Jefferson County, Pennsylvania
Jefferson County sits on the western Allegheny Plateau in northwestern Pennsylvania, with Brookville at the Interstate 80 and US 322 crossing and Punxsutawney, the larger borough, to the south. Powdered metal, wood products and gas processing anchor employment, and new activity concentrates in the Punxsutawney and Brookville industrial parks; steep plateau terrain and legacy bituminous mining limit sites outside the boroughs.
