I few weeks ago we were were doing the section through Roan Mtn and stayed at the Over Mountain Shelter. The shelter is a few .10s off the trail. On the way from the blue blaze and AT intersection to the shelter we saw these huge white headed plants about 6-7 tall. I remarked they looked alien. Some were really close to the trail. When we got back to the matrix we found an article that what were had seen was Giant Hogweed which can give 3rd degree burns. Or was also on the climb or from the intersection trail north. Very innocent looking weed but sure could ruin a hike.
