About this map

Pine Grove Mills and the surrounding agricultural valleys of Ferguson and Franklin townships define this landscape at the intersection of Centre Co and Huntingdon Co. The terrain is dominated by the steep parallel ridges of Tussey Mountain and Leading Ridge, which enclose Harrys Valley and the vast Rothrock State Forest. Local history is anchored by the presence of industrial remnants like Monroe Furnace and the Pennsylvania Furnace Cem, alongside established rural centers such as Baileyville, Rockspring, and Neffs Mills.

The southern portion of the map highlights the academic and conservation footprint of the region, featuring the Pennsylvania State University Experimental Forest and the University Dam on Shaver Creek. Transportation patterns are marked by a network of rural routes like Whitehall Road and the path of an Old R.R. Grade winding through the northern gaps, reflecting the transition from early resource extraction and milling to modern forestry and research land use.
