On sunday it looked like there were two red boats pinned in the boogie below screaming 1/4 mile on the lower run. If folks didn't see the boat in black rock, maybe its one of the red boats in lower?
I looked at one of the pinned boats below screaming 1/4 mile. Its hard to get to, the water is hauling ass, and the grab loops are underwater. I personally would leave it there until the water comes down. Its probably now worth messing with unless you have a desire to spend a lot of time on a technical rope system rescue.
