2019 Map of Mammoth

About this map

Chestnut Ridge dominates the eastern elevation of this Westmoreland County landscape, where the headwaters of Jacobs Cr and Welty Run carve out the local topography. This 2019 survey captures a network of smaller residential clusters and crossroads communities like Kecksburg, Norvelt, and Trauger, many of which remain distinct from the larger surrounding townships. Notable water bodies such as Mammoth Lake and Loyalhanna Lake serve as key landmarks within the drainage basins of Sewickley Cr and Hurst Run. For those tracing local history, the map identifies specific genealogical sites including Saint Lukes Cem near Humphreys and Brothers Cem in the southern reach. The transition from the more developed corridor near Pleasant Unity and United to the more wooded terrain of Possum Hollow illustrates the contemporary balance between residential settlement and the upland forests of southwestern Pennsylvania.
