Hi- while climbing at Mary's Bust on July 28, a fellow in his 50's or so found a gri-gri below the route "Deceiver", downhill from there. He said it had a couple identifying colors on it, and he took it with him. He said he lived in Waltonia, a small neighborhood also in the Big Thompson Canyon, not too far from the crag. I bet you could locate him and get it back, if you tried. good luck!
