Upper Tract and Brushy Run anchor this section of the Potomac Highlands, where the South Branch Potomac River and its North Fork cut through the dramatic ridges of the Monongahela National Forest. The landscape is defined by the massive spine of North Fork Mountain and the prominent River Knobs, which give way to notable geological features like Roy Gap and Seneca Rocks. The presence of numerous named water sources, including Hermit Island Spring, Eagle Rock Spring, and Waggy Farm Spring, suggests a topography rich in karst features and perennial flows that have sustained valley settlements for generations.
