Trough Couloir
Considered the standard Winter ascent route of Longs Peak, The Trough Couloir is a steep NW-W facing couloir that often holds snow into the late Spring, but is known for variable conditions. Beware of avalanche danger and rockfall from climbers above you and be sure what you're planning to ski is filled in.
