I remember seeing old discussion in the yahoo archives of a dangerously large rapide hanging from one of the final anchors in Mystery canyon. There appears to be a new one in place. I was lucky enough to draw a permit for labor day and found the bolts at the final rap into the narrows double rigged. There was new looking bright red webbing tied off with a "regular" quick link while the chains held a shiny CAMP rapide large enough to pass a BD positron screw-lock through it. I couldn't get it open with my fingers and I wasn't carrying a wrench. Maybe the next forum reader who draws a mystery permit could toss an adjustable wrench in their pack and pull the bloody thing.
