A private small raft flipped near the Class V Iron Ring Rapid, throwing all three boaters into the river. Two of the party were able to swim ashore, however one of the boaters, 62-year-old Norman LaHugh Cassell of Richmond, Virginia, appeared to be unconscious in the water. Caswell was pulled from the water by off-duty commercial rafting guides, who began CPR, with Rangers and EMS arriving on scene to assist.
