In this episode, we follow avalanche patrol crews as they work through the night to keep a mountain safe before dawn skiers ever set foot on it — checking snowpack stability, gearing up in sub-zero cold, hauling explosive charges out to known slide paths by headlamp, and triggering controlled releases to bring unstable snow down on their own terms, all set against the long, quiet stretches of radio static and waiting in a patrol shack or snowcat cab while wind and snowfall are tracked hour by hour, until the slopes are confirmed safe just before sunrise.
