Observation Rock is an apt name for this remnant vent on the north side of Rainier, about 4 miles NNW of Rainier's summit crater. Understandably, Ob Rock's summit provides unmatched views of the north faces and glaciers of Rainier. Even with its friable nature, Ob Rock is a popular objective. This route is a beginner ice climb on a north-facing ice sheet. The peak can be climbed in a day from the Mowich Lake trailhead. Some crevasses exist but these are mostly avoidable.
