I came upon this anchor when desecending cascade creek in Ouray this past weekend. One end of the rope was tied around a tree about 10 feet above. The rope hung down with a figure 8 on the bottom with a quick link. This part was rubbing across a rough edge. There was at least 1 group of 2 in front of us that used this. Needless to say, this became part of my Canyon Trash.
