About 100 meters to east of the cup marked rocks is a fenced section. In hear at least 5 meters of well built souterrain remain. One problem the roof was taken away and the area has filled in over the years. Only a wee hollow marks the shape of the site. Photographs won't do much good here until, hopefully, an excavation. The fence is a precaution to stop beasts and humans but not drews from falling in.
