The Story
Between 1790 and 1850, the streams of the Juniata region powered dozens of charcoal iron furnaces and forges whose ruins still dot the landscape. Juniata iron earned a reputation as the finest in America, prized for its purity and strength in an age before industrial steelmaking. The industry's reign ended in the mid-19th century as ironmakers shifted to coal and coke fuel, drawing production toward the coalfields and cities.
Why it matters
The Juniata Valley's charcoal iron industry stands as a landmark chapter in early American manufacturing, and its decline illustrates how the shift from charcoal to coal reshaped where and how the nation forged its metal.

Bedford Furnace
Cromwell Township, PA · est. 1947
Completed around 1788, Bedford Furnace was the first iron furnace in the Juniata region, launching an industry that would define central Pennsylvania for generations. Built along Black Log Creek, it produced charcoal iron—smelted using vast quantities of hardwood charcoal from the surrounding forests—and became renowned for quality. It stood at the leading edge of the young nation's westward-spreading iron industry just as the Constitution was being ratified.
Civilian Conservation Corps Cabins
Bratton Township, PA
During the depths of the Great Depression, Franklin Roosevelt's New Deal put hundreds of thousands of unemployed young men to work through the Civilian Conservation Corps, founded in 1933. Enrollees lived in camps and built the trails, shelters, and cabins that still shape America's state and national parks and forests. These cabins in the Pennsylvania countryside are a surviving piece of that effort — hand-built by a generation that found both dignity and a paycheck in conserving the land.
Huntingdon County
Huntingdon, PA · est. 1982
When Pennsylvania carved Huntingdon County out of frontier Bedford County in 1787, the young commonwealth was still ratifying the new federal Constitution. The county took its name from Selina Hastings, Countess of Huntingdon, an English patron whose gifts helped the fledgling University of Pennsylvania — a nod to the transatlantic ties that still shaped early American learning. Its valleys of fertile ground, iron ore, timber, and rushing water power drew settlers who would turn the region into a working landscape of farms and forges.
David R. Porter
Huntingdon, PA · est. 1955
David R. Porter made his home in this house while building a career that carried him from the iron furnaces of central Pennsylvania to the governor's chair, which he held from 1839 to 1845. Affectionately called "our own Davy R.," he embodied the era when ironmasters were both industrialists and political leaders. His son Horace, born here in 1837, went on to distinction as a soldier and diplomat.
