Mosby Spring

Two springs can be found along the Signal Knob Trail. The first is the one that flows out of a pipe, just off the Signal Knob Trail, just past the Forest Service Cabin. You will hear it rushing. The second is located to the left, where it turns sharply to the right and climbs steeply. The cement box has a pipe that comes out of it. The spring doesn't stop flowing in hot temperatures, at least not from what I have seen. The spring by the cabin is not.
Directions:
Take Fort Valley Rd. / Rt. 678 to the George Washington National Forest. Take a right into Signal Knob parking lot. The Signal Knob trail can be found on the right-hand side of the lot. Continue up the trail, crossing the wooden bridge. The forest service cabin is the first spring. The second spring, which is harder to miss, is located further up the trail.
