Mather and Jefferson serve as the primary hubs in this section of southwestern Pennsylvania, where the landscape is defined by the winding course of Tenmile Cr and its southern fork. The settlement pattern reveals a series of planned residential clusters and industrial-era hamlets, including Williamstown, Braden Plan, and the descriptively named Pitt Gas near the Monongahela River. These locations, often established to support local extraction and transport industries, sit alongside rural outposts like Khedive and Lippincott.
