Cougar Creek West

Cougar Creek West is a serious ski-mountaineering line above Cougar Creek in the West Rogers area of Glacier National Park, accessed via the Ross Peak Designated Access Route from the Loop Brook winter parking. From the Ross Peak access corridor, you work up through the same tree wedge and avalanche path used for the east face (route 207), then commit into a steep, solar gully that feels fully exposed from the start.

Above the lower cliff band you trend northwest around 1,800 m into the main gully, which gives a clean handrail all the way to the ridge. The upper entrance is usually free of a direct cornice, but large cornices hang nearby, so you want tight group management and short exposure time on the ridge. This zone sits in a strong sun pocket on the climb, then rolls over into a big, shaded feature above cliffs on the north side, so expect strong temperature gradients, wind effect, and complex loading patterns.

The descent starts in an off–fall-line trough that skis well and naturally funnels you into the main line on the east side of the face. From there it’s a sustained fall-line run back into the Cougar Creek drainage with real overhead hazard and no easy outs once you’re committed. You need stable conditions, a clear read on the upper start zone, and a pre-trip visual inspection of the whole line from below before pulling the trigger.

Exit by following Cougar Creek down and then rejoining the Ross Peak Designated Access Route back to Loop Brook, staying within the signed corridor where required.
