The Channels State Forest in Abingdon, Va. features a natural rock formation and abandoned fire tower. Parking area on Hayters Gap Rd with moderate uphill hike to the top. Perfect views and plenty of places to explore, a must see!
The Great Channels are an unusual geological maze of large sandstone boulders and eroded crevices.
Per a park brochure: "At the crest of the mountain, within the Natural Area Preserve, are the Great Channels of Virginia, impressive formations of 400-million-year old sandstone outcroppings. Geologists conclude that the Channels were likely formed while the high elevation sandstone cap was under the influence of permafrost and ice wedging during the last ice age. These forces shattered and enlarged joints in the sandstone caprock."
