GSW Fall Field Trip! Sat. Dec. 20, 2025

Posted on November 25, 2025 by | Comments Off on GSW Fall Field Trip! Sat. Dec. 20, 2025

USGS Geologist Peter Valley will lead a hike along Difficult Run to the Potomac River below Great Falls. Along the way are metagraywackes, migmatites, and even some petroglyphs! The parking area for Difficult Run Stream Valley Park is small and fills up quickly; therefore, we will arrange carpools.

Meet at 8:00 am at the Reston Town Center Metro station, on the south side in the parking area adjacent to the bus stop and roundabout at the Kiss and Ride. Carpools will be arranged from this point to the Difficult Run trailhead. Wear sturdy shoes or boots that may become wet. This trail is very rocky and steep in places, requiring some rock scrambling in sections. Please bring a lunch and water.
