Copper Peak North Couloir

The marquee line on Copper Peak’s north side is a steep, aesthetic couloir with real exposure from the first turn. Expect a confined upper slot with rock walls and frequent rock, ice, or cornice features guarding the entrance, then a sustained fall-line runout that stays shaded and cold.

Snow can be highly variable at the choke: wind-scoured and firm, or loaded with stiff wind slab. Overhead hazard from cornices and rockfall is common, and sluff can build quickly in the gut, especially after storms. Treat the line as serious no-fall terrain; a mistake high in the couloir has consequences all the way to the fan.

From the usual high point on the ridge, most parties boot the final section to the entrance, often transitioning on a small, exposed platform. Many skiers belay the first person into the line when coverage is thin or the cornice is tricky to breach. Once committed, there are few safe islands to regroup until you are well into the lower fan.

Best in settled winter or early spring when the pack is deep and the upper walls are filled in, but before intense solar input starts shedding cornices and rock onto the line. Conservative avalanche timing and a tight group management plan are mandatory here; this is not a good first big couloir for newer partners.
