George Washington surveyed it in 1750, and Thomas Jefferson bought the largest limestone arch in North America above in 1774. At 200’ tall, it’s higher than Niagara Falls. See if you can find the people in the photo. It’s an NPS affiliate, managed by Virginia State Parks. There’s a pretty 1.7 mile trail up under and past the arch along Cedar Creek, with many steps, interesting rock formations, heron below, woodpeckers, chickadees and other birds.
