A Boy Scout leader died on a troop rafting trip on a popular whitewater stretch of the Snake River.

Craig McCuistion of Rexburg, Idaho, drowned Friday after being thrown from his raft when it hit a rapid known as Three Oar Deal. McCuistion was leading a Boy Scout rafting trip with other adults.

Lincoln County Coroner Michael Richins says McCuistion was wearing a life jacket but was sucked under by a whirlpool.

Another trip leader was thrown from the raft but was able to swim away, Richins said. All of the Boy Scouts stayed in the raft and were unhurt. Richins said he did not know how may Scouts were on the trip.

McCuistion was 50, according to an obituary in the Idaho Falls Post Register.
