Central Pennsylvania is wilder and more forested than I had imagined. Looking at an aerial photo you can see the green parallel ridges of the Appalachians separated by flat agricultural valleys south of US-80 and the stream and gorge riven Pennsylvania Wilds north of 80. It's some of the more remote country in the east. Rothrock is the closest, just south of State College, and has the most developed trail system.
Deforested in the 1800's for charcoal used in the local iron industry, it was purchased by the state at the turn of the century when the forest was depleted and iron production moved closer to coal and the industrial centers. The forest has since regenerated and is managed for recreation and sustainable forestry.
This section of Pennsylvania is unglaciated, leaving jumbles of square rock along and down the ridges with soils concentrated in the valleys, broken and loosened by millennia of freeze and thaw. Ridge tops seem to climax in oak, valleys in hemlock and white pine over massive drifts of rhododendron and laurel. Eastern hardwoods cover the hillsides.
