¡Ay Chihuahua!

Expedition kayakers Erik Boomer and Ben Stooksberry take on the mile-deep Barranca Candameña in the Wild West of Chihuahua, Mexico. At the put-in, with heavy rain filling the river, the team weighs the danger of flash flood and the specter of narcos against their goal to be the first to descend one of the most spectacular canyons on Earth by kayak.
