Whitehorse Mountain/Northwest Shoulder

A strenuous early season climb with 7,000 ft of elevation gain, a glacier crossing, possible moat problems, ending with a short rock scramble with some exposure. Great views in all directions from the summit and lots of solitude. This is a long climb, requiring an early start, with significant blow-down adding to the challenge. Times: 12-14 hr trailhead to summit.

Getting There

Drive north on I-5 through Everett. About 11 mi north of Everett turn right (east) onto SR 530 to Arlington. Continue on SR 530 about 23 mi east of Arlington (5 mi west of Darrington) to Shell Station at Mine Road/387 Av. Turn right (south) and in 0.5 miles park at the closed bridge over Moose Creek. Walk the road, turning left at each of the next two forks. Shortly after crossing Furland Creek, the trailhead is marked “Niederprum Camp” (on the right, about 2 mi from the store).

APPROACH

Hike up the Niederprum Trail about 2 mi to 3,000 ft. Leave trail here and make gently rising traverse to the left (south) through forest for about 0.5 mi to a wide couloir which should be snow filled until early July. In late season, it is best to take the trail to its end, then traverse below cliffs and above brush to near head of the couloir.

Ascend couloir to Lone Tree Pass at 5,000 ft, then turn left and traverse east and down about 500 ft to near a small lake. Make a long rising traverse east eventually reaching a broad open slope. Ascend slope/gully to High Pass at 6,100 ft. Cross the pass to Whitehorse Glacier.

ASCENT ROUTE

Ascend the glacier to the snow ridge, then up the ridge to the moat near the summit rock. Moat is crossable in early season. May need snow anchors to belay across to rock. Final rock is a short scramble. Somewhat exposed. Rope leaders may want two to four stoppers.

DESCENT ROUTE

Descend the climbing route.

TRIP PROFILE

SEGMENT TIME (HR) ELEVATION GAIN (FT)
Seattle to Trailhead 1.5
Trailhead to High Pass 7-8 6,100
High Pass to Summit 2-3 800
Summit to Trailhead 3

EQUIPMENT

Standard alpine equipment and crampons. Some parties bring glacier gear but trip reports indicate that it is not always used.

NOTES

Car camp  is recommended as this is a very long climb and requires an early start in the morning. The other climbing route via the Whitehorse Glacier should be avoided as it is dangerous (avalanches, rockfall). This climb is an excellent conditioner in early season. Consider stopping at the Texaco station (where Whitehorse Merchantile used to be) and looking at route before climb (Lone Tree Pass is not obvious from directly below).

Bridge over Moose Creek closed and barricaded for safety reasons in 2008.  You can car camp at the closed bridge.
