2016 Map of Mammoth

About this map

Chestnut Ridge dominates the eastern landscape of this Westmoreland County region, where the terrain shifts from agricultural valleys to the rising highlands. The settlement pattern is characterized by numerous small villages and crossroads communities including Pleasant Unity, Kecksburg, and Norvelt, reflecting the area's deep-rooted residential history. Water resources are plentiful throughout the quadrangle, notably Loyalhanna Lake in the north and the recreational Mammoth Lake near the center. The southern portion of the sheet marks the transition into Fayette County at Acme, where Acme Lake and Bear Rocks sit near the county line. This map reveals a complex network of local roads such as Moccasin Hollow Rd and Saloon Cutoff Rd that connect these historic settlements across a landscape defined by creeks like Sewickley Cr and Jacobs Cr.
