I love these markers called Sight Over Cone; had to do a lot of research to finally find their name. Part of the middle cone is missing. Also, in the distance is Shenandoah National Park and the Great Smoky Mountains (I think it says about 40 plus miles in the distance). In the video I have additional pictures and IDs of these markers as there were about three or four of them.
Left to right cones: Toxaway Mtn, Whiteside Mtn, Tanasee Bald, ? (I can't read it using the Original picture)
