These caves are in the Burnsvulle Cove in western Virginia, and all have locked gates. Access is controlled by the BCCS, which has number of expedition weekends every year when the the caves are open to cavers outside of the BCCS, and trips can be organized outside of the expedition weekends. So the caves are open for caving, although protected by controlling access.
Most all of my decent photos from this area are on slides, which take time to digitize. But I was there last weekend at the fieldhouse and bonfire. Some recent pics show that. Here are the rest of my shots from the weekend. I wasn't really there to take photos, but took some nonetheless.
