Mt. Vernon Springs, Siler City, NC

Just next to the road. A shelter is built above it and a concrete enclosure surrounds the source. The water comes from a pipe that is about at ground level. You will see a little pool there. Non-stagnant water can be obtained if your cup is held above the level the pool. It is easier to obtain non-stagnant water in the morning.
There is also a church, as well as another building. It's about 1.2 mi west of Hwy 87 at the intersection with Greensboro Chapel Hill Rd. It is marked with the words "Spring Friends Meeting". Concrete steps lead down to it from right next to the driveway.
