Geography
Jacobs Creek, between Chaintown and its mouth, cuts a deep gorge through the Fayette Anticline, exposing many rock outcroppings and even exposures of the Freeport Coal seam.
The geography of Jacobs Creek allowed early civilization in the Jacobs Creek Valley as early as 1768 when western Pennsylvania was opened to settlement by the Treaty of Fort Stanwix. According to Rambling in the Valley of Jacobs Creek (Medsger & Rowe):
Various industrial enterprises have been associated with the history of this valley. Among the first were the manufacture of salt and iron. By the treaty of Fort Stanwix in 1768 this region was opened for settlement and many people from the eastern part of the state were locating in this "land of promise". Both salt and iron were in demand, they were expensive and hard to procure, hence men of enterprise naturally sought means to supply these demands. George Dallas Albert in his "History of Westmoreland County", says that, "Foremost of the wants of these early settlers was the want of salt." He also states that "in the Youghiogheny region, twenty bushels of wheat was not thought an unfair exchange for a bushel of salt; or a cow and calf for a similar amount."
Other geographic features of the valley include two waterfalls: Freeman Falls and Creek Falls.
