The geology of Wolf Township played a role in its history. Limestone was quarried west of Hughesville for use as lime. Lime is used in large quantities as building and engineering materials and as chemical feedstocks, among other uses. Lime industries and the use of many of the resulting products date from prehistoric periods in both the Old World and the New World. Wolf Township was also the home to several Pennsylvania Bluestone quarries. Pennsylvania Bluestone has many uses, from cut dimensional stone used in patios, walkways and stair treads to architectural stone used in buildings. It is also used for wallstone, decorative boulders, natural steps and other landscape features. The name "Pennsylvania Bluestone" is due to its predominantly blue color and because the majority of stone is quarried in Pennsylvania.
Early settlers and industry
David Aspen was the first white settler to live within the borders of what is now Wolf Township. He was scalped during American Revolutionary War, when his and other settlements throughout the Susquehanna valley were attacked by Loyalists and Native Americans allied with the British. After the Wyoming Valley battle and massacrein the summer of 1778 and smaller local attacks, the "Big Runaway" occurred throughout the West Branch Susquehanna Valley. Settlers fled feared and actual attacks by the British and their allies. Homes and fields were abandoned, with livestock driven along and a few possessions floated on rafts on the river east to Muncy, then further south to Sunbury. The abandoned property was burnt by the attackers. Some settlers soon returned, only to flee again in the summer of 1779 in the "Little Runaway". Sullivan's Expedition helped stabilize the area and encouraged resettlement, which continued after the war. Abraham Webster was another of the early settlers to be attacked, only he survived and returned to Wolf Township twelve years after the Big Runaway. His entire family had been killed but he returned with a new wife and re-established his home. The earliest industrial venture in Wolf Township was a gristmill constructed in 1816. A wool carding mill was built in 1842. There were also several sawmills in the township that were part of the lumber industry that covered much of Pennsylvania during the late 1800s.
