Cabin Branch Pyrite Mine Trail (0.3 miles; 0.5 km)
This short trail descends down to an open expanse above the banks of the Quantico Creek, once the site of the Cabin Branch Pyrite Mine (1889-1920). During the mine’s operation, more than 200,000 long tons of pyrite was brought to the surface and processed into sulfuric acid. This was used to make soap, fertilizer, and gunpowder. This trail can be reached by parking in lot D and traveling along the Pyrite Mine Road for about ten minutes until you reach the trail marker on your left.
