Nooksack Traverse
North CascadesBest Apr–May
A three-day traverse crossing five glaciers over Mount Shuksan, through the Nooksack Cirque, and out past Ruth Mountain.
About This Trail
The Nooksack Traverse crosses Mount Shuksan from the White Salmon Glacier to the Nooksack Cirque, linking five glaciers over three days in some of the most committing terrain in the North Cascades. The route starts at the Mt. Baker ski resort parking lot, drops 1,000 feet through old growth forest into the White Salmon Valley, then climbs the White Salmon Glacier with buried crevasses and steep switchbacks on rope. The Winnie Slide and Curtis Glacier push the route onto Shuksan's hanging glacier system before dropping into the Nooksack Cirque on the Crystal Glacier.
Day two crosses the cirque floor, one long exposed avalanche path flanked by ice cliffs and thousand-foot drops. The Nooksack Headwall presents massive shrund hazards and a 55-degree traverse that demands precise route-finding. The exit trends toward Icy Peak and Ruth Mountain before descending out.
This traverse requires a minimum two-day weather window with stable snowpack. Late spring corn conditions are ideal, but the window is narrow: too early and the snow is unstable, too late and the shrunds open up. Parties that attempt this route carry full glacier gear, rope up for every glacier segment, and move with the kind of deliberate pace that keeps everyone alive on 55-degree traverses above cliffs. Route-finding in flat light on the cirque crossing has turned back strong parties.

Safety & Considerations
Persistent Hazards
- Crevasses on White Salmon, Curtis, Hanging, Crystal, and Nooksack Glaciers
- Avalanche exposure throughout, especially the Nooksack Cirque crossing
- Ice cliffs and massive shrunds on the Nooksack Headwall
- 55-degree exposed traverses above 1,000-foot drops
- Route-finding extremely difficult in flat light or whiteout
- Multi-day commitment with no easy bail options once past Shuksan
Getting There
Start at the White Salmon parking lot at Mt. Baker Ski Area off SR 542. Free parking in the upper lots during spring. The ski area closes for the season in late April but the road stays open.
From the ski area, skin across the lower resort terrain, then descend 1,000 feet through old growth forest with creek crossings into the White Salmon Valley. The White Salmon Glacier climb begins with two route options: a direct exposed line or a tree-protected slope. Rope up before the glacier. The traverse runs south over Shuksan's summit plateau, drops the Crystal Glacier into the Nooksack Cirque, crosses the cirque, and exits past Icy Peak toward Ruth Mountain.
Requires a confirmed two-day clear weather window minimum. Most parties depart at dawn from the ski area parking lot. Patience in waiting for the right window is the defining feature of planning this traverse. A rain event followed by fresh snow and clearing skies produces the best conditions.
