Lycoming County, Pennsylvania
Lycoming County is Pennsylvania's largest county by area, spanning the West Branch Susquehanna valley and the northern ridges, with Williamsport, Montoursville, and South Williamsport forming its urban core. Marcellus Shale gas anchors the economy — the county is among Pennsylvania's top producers with more than a thousand producing wells — and its designated Montoursville–Muncy growth corridor, not the ridges, is where industrial sites are planned.
