Created on March 11, 1839 from parts
of Venango and Armstrong Counties and named for the Clarion River. Clarion, the
county seat, was incorporated as a borough on April 6, 1841.
Formed on land acquired from Indians by the Treaty of Fort Stanwix in 1784, it
was first owned by the Holland, Pickering, and Bingham land development
companies. Settlement began in 1797, and a lumber industry sprang up which
relied on floating logs down the Clarion River to the Allegheny. Boat building
developed and lumber was also used for making charcoal- needed for a local iron
industry- but the lumber based economy played out by 1900 because the trees were
not replaced. Cook Forest State Park is the home of the only significant stand
of primeval trees in the state. An oil boom lasted from 1869 to 1879; bituminous
coal mining began in 1877. Surface strip bituminous coal mining has been in
operation since 1920. Having both fire clay and natural gas, a pottery industry
flourished in the nineteenth century. The Philadelphia and Erie Railroad was
built through the county in the 1870s. The 40,000 population of 1880 was not
equaled again until the 1980 census. There is a farming tradition; in total
receipts from farm products Clarion ranks about 44th among the 67 counties.
Farms occupy 31 percent of the land. There were Underground Railroad stations at
Clarion, Rimersburg, and Shippensville.
As reported by the Census Bureau, the county has a total area of 609 square miles (1,577 km2), of which, 602
square miles (1,560 km2) of it is land and 7 square miles (17 km2) of it (1.07%) is water.
