Observation Rock/North Face

Observation Rock via the North Face is a Grade II ice climb.

Getting there

From Buckley drive south on SR-165, eventually crossing the Carbon River bridge, to a road junction with the right, uphill fork signed for Mowich Lake. Take this right fork all the way to the lake (4,929 ft).

APPROACH

Follow the Spray Park Trail heading south from the lake. Shortly there will be a junction with the Wonderland Trail. Continue south, then east on the trail, up into Spray Park. Near the high point on the trail at approximately 6,400 ft a cairn marks a climber’s path which takes off north toward Observation Rock.

This path becomes indistinct around 7,200 ft in moraines. From here there are numerous ways to approach the North Face of Observation Rock by contouring southwest. Some parties aim for the small lake at 6,583 ft to ascend snow; this can reportedly avoid some tedious scree.

ASCENT ROUTE

Ascends the steep finger of the Flett Glacier, aiming southwest for Observation Rock’s summit. There is enough ice for four to five pitches, steepening to about 50° near the top. The first pitch is usually simul-climbed; then parties can swing leads to the top of the glacier. There is plenty of room for two to three parties to climb at once, with some variation in steepness and snow cover from left to right. From the top of the glacier, unrope and scramble to the crumbly summit for fine views of Rainier’s north side.

DESCENT ROUTE

The best descent is to scramble down to the south and east of Observation Rock. Descending to the west puts one back on the crevassed Flett Glacier which may prove impassable late in the season. Then follow the climbers’ trail back to Spray Park and then the main trail back to Mowich Lake.

Scheduling and Permits

  • Must be done on or after July 1 for Intermediate Ice credit.
  • Difficulty can vary greatly as conditions change. Trip leaders are asked to use judgement in awarding Intermediate Ice credit in conditions where it is unwarranted. Students should understand that achieving the summit does not guarantee credit. Characterizing a route on a given day as "challenging enough" is obviously subjective.
