2013 Map of Derry

About this map

Chestnut Ridge dominates the eastern landscape of this Westmoreland County study, rising above a network of small coal and industrial settlements. The borough of Derry serves as a focal point, situated near Ethel Springs Lake and the smaller hamlets of Peanut and Burds Crossing. The southern portion of the map is defined by the Loyalhanna Creek, which carves through the Loyalhanna Gorge, passing Buttermilk Falls and the community of Idlepark. This area demonstrates a dense cluster of naming conventions tied to the local geography, with numerous hollows like Rock Hollow and Saint Clair Hollow branching off the primary watercourses. The transportation network is anchored by the Lincoln Hwy and State Route 217, connecting older centers like Youngstown and New Derry with specialized sites such as the Kennametal Reservoir and Latrobe Reservoir.
