About this map

Lehigh Furnace sits at the base of Blue Mountain in this mid-1960s survey of Lehigh County, documenting a landscape where industrial history meets rural Pennsylvania Dutch country. The map traces the rugged northern boundary of Heidelberg and Lynn townships, defined by the Appalachian Trail as it crosses Bake Oven Knob. While many of the area's slate quarries are clustered near Slatedale and Emerald, the interior is a network of small hamlets and family-named landmarks.

Genealogists and local historians can locate several historic houses of worship, including Heidelberg Ch and Wesenberg Ch, alongside rural schools like Peters Sch. The transportation history of the region is preserved through the lingering Old Railroad Grade and the Covered Bridge on Jordan Creek. The presence of State Game Lands No 217 and the Trexler Game Preserve highlights the shift toward conservation in this agricultural valley.
