South Mountain and Green Ridge dominate this mid-century view of the Pennsylvania-Maryland borderlands, where narrow valleys support a network of small settlements and early industrial sites. The southern half of the map reveals the historical influence of the iron industry, anchored by Maria Furnace and the namesake Iron Springs. These locales, along with Gladhill (Greenstone PO), were closely tied to the Western Maryland railroad, which provided the essential transport link through the gaps of Jacks Mountain.
