Blue Mountain serves as a massive geologic spine across this 1914 survey, dividing the ridge-and-valley landscape of Monroe and Northampton Counties. This era is defined by the heavy infrastructure of the Lehigh and New England RR and branches of the Delaware Lackawanna and Western RR, which service the region's industrial hubs like Pen Argyl and the slate-producing center at Chapman Quarries. The map reveals a dense network of early 20th-century rural education, featuring numerous named institutions such as the Michael Valley School, Bushkill School, and Steckel School.
