Leidy Natural Gas Boom

Leidy Township, Clinton County, Pennsylvania

Marker Inscription

Against expert advice, Dorcie Calhoun drilled Leidy Township's first successful deep gas well about a quarter-mile south of here. On January 8, 1950, the well hit natural gas at a depth of 5,659 feet, and for a time it brought up an estimated 15 million cubic feet per day. This news attracted national attention, and within months more than 30 companies and independents were drilling here before production ceased.

The Story

In the winter of 1950, wildcatter Dorcie Calhoun ignored expert opinion and drilled deep into the hills of Leidy Township in search of natural gas. On January 8 his well struck gas at more than 5,600 feet, briefly gushing an estimated 15 million cubic feet a day. The strike made national news and set off a frenzy: within months more than thirty companies and independent operators were drilling across the township, chasing the boom before the field's production wound down.

Why it matters

The Leidy strike was a landmark in Appalachian deep-gas exploration, foreshadowing the region's later emergence as one of America's great natural-gas provinces.

Cameron County

Emporium, PA · est. 1982

Cameron County was pieced together in 1860 from four neighboring counties and named for U.S. Senator Simon Cameron, the powerful Pennsylvania politician who would soon serve as Lincoln's first Secretary of War. Its seat, Emporium, took shape in the 1860s in a landscape of deep forests, and lumbering drove the early economy. Flagstone quarried in the county was later chosen for the Tomb of the Unknown Soldier at Arlington.

Sylvania Electric Products

Emporium, PA · est. 2021

Founded in 1907 in the small mountain town of Emporium, Sylvania Electric grew into a national name in vacuum tubes and electronics. During World War II its workers—largely women—produced vacuum tubes for the proximity fuze, a device that let artillery shells detonate near their targets and dramatically improved accuracy. The reliance on a female workforce led Collier's to dub Emporium "Girls Town USA," and the Poplar Street plant ran until 1990.

Austin Flood Disaster

Keating Township, PA · est. 1994

On September 30, 1911, the concrete dam of the Bayless Pulp and Paper Company — built only two years earlier, nearly fifty feet high and 534 feet long — gave way, hurling a wall of water and debris down Freeman Run into the towns of Austin and Costello. At least 78 people were killed and the mill towns were devastated. Pennsylvania's second-worst single-dam disaster, it spurred a 1913 state law to regulate dam construction.

Karthaus Furnace

Karthaus Township, PA · est. 1948

Near this spot Peter Karthaus built an iron furnace in 1817, part of the early push to work the ore and timber of Pennsylvania's Clearfield County wilderness. Rebuilt in 1836, the furnace made a notable experiment in 1839 as one of the earliest in the region to try coke in place of charcoal for smelting iron. The venture proved short-lived and was abandoned that same year, but it foreshadowed the fuel revolution that would soon transform American iron.
