Clarion County was carved out of Venango and Armstrong counties in 1939, and is named for the Clarion River, as is the county seat town of Clarion. The 54th County to be formed, the county was incorporated on April 6, 1841. Clarion County is rich in mineral resources and was once one of the Wealthier counties in the state due to the large number of Iron Furnaces. From 1845-1854, Clarion County Produced one-half of all the Iron in Pennsylvania. This industry dwindled and died after the Civil War due to the emergence of the Steel Industry.
Clarion county occupies a central position in Western Pennsylvania, lying but six miles north of a line drawn east and west through the middle of the State. Three Main Waterways occupy the County; The great central one of the Clarion River, comprising three-fourths of the county; the northern, where the edge is drained by streams falling into Tionesta Creek and the Allegheny; and the southern, whose streams take their course to Redbank, with the exception of Catfish and Black Fox Runs, emptying into the Allegheny. The average elevation of the county above sea level is about 1,300 feet. The lowest point in the county is at the mouth of Redbank, 851 feet; the highest, the heights to the southeast of Fryburg, on Mr. Denslinger’s farm, which are 1,775 feet above ocean level. As a rule, however, the summits of the northern half range lower than those of the south; the former ranging from 1,500 to 1,600 feet, while the latter are from twenty-five to fifty feet higher. The highest point south of the river is the peak near St. Nicholas Church, in Limestone township, which claims an elevation of 1,750 feet above sea 1evel. The summits on the Clarion-Redbank divide range from 500 to 625 feet above water level in Redbank Creek. The general character of the surface is hilly — almost mountainous — near the water courses, and undulating in the uplands. Here and there on the line of the dividing ridges rise bold, isolated knobs, usually stream sources. Their crests are in most cases cleared and cultivated to the summit; some are capped by a picturesque grove or orchard. Streams and springs are everywhere in profusion. A magnificent view of the great horseshoe bend in the Allegheny, with East Brady and Phillipsburg in the distance, is to be had from the heights, near the junction of the East Brady and Phillipsburg roads in the neck; where the silver Allegheny, after sweeping around the precipitous slopes below Catfish; East Brady, and Phillipsburg — a distance of eight miles — doubles on itself, till less than a mile measures the isthmus. A beautiful panorama of woodland heights and the romantic gorges of the Allegheny and Clarion greets the eye after ascending from Foxburg on the Pittsburgh and Western Railroad. The view of the Clarion, far below, is especially fine, and in mountainous grandeur almost equals the scenery of Kittanning Point, on the eastern slope of the Alleghenies, besides having the additional charm of water scenery. The stream that enters the Clarion at this point has, in the lapse of ages, worn its way through the rock and formed a romantic glen whose beauties every year gain increased appreciation. Here verdure-capped cliffs arise perpendicular; detached bowlders of immense size and curious forms add a unique beauty to the scene; and deep down in the shade the streamlet seeks its way, plashing over the rocks, to pay its humble tribute to the river below.
