Big Run (North Fork South Branch Potomac River tributary)
River in West Virginia, United States
Big Run
Big Run, just after it leaves the marshland and enters the forest, below the beaver dam at river mile 12.4. Monongahela National Forest, West Virginia, 8 October 2017
The river begins as a series of gullies through an open marshland just south of the northernmost bend in Forest Road 112. Between river mile (RM) 12.8 and 12.4, a series of beaver dams causes the valley to transition from wetland into a string of lakes. From the last beaver dam at RM 12.4, a recognizable river emerges. The open field ends and the river enters a forested ravine.
Big Run joins with tributaries Elk Run at RM 5, Teeter Camp Run at RM 3.6 and Sawmill Branch Run at RM 3.2.
The river empties into the North Fork South Branch Potomac River just outside of Cherry Grove, along Snowy Mountain Road just across the bridge over the Potomac.
This is one of a number of Potomac tributaries known as Big Run, including Big Run at Romney and Big Run at Harper.
