Japan’s Jigokudani became a sensation when hot springs were constructed for the Hell Valley snow monkey troops. The monkeys get important help from the hot springs in the valley, fed by warm volcanic waters, but their survival is a communal effort in a complex society of rank and privilege where each knows their place. Snow Monkeys airs Wednesday, April 23 at 8 p.m. (ET) on PBS (check local listings).
