Although not the highest of the Tatoosh peaks, Pinnacle's central position and attractive form have made it the most popular ascent in the park. When the Mazamas climbed it on July 26, 1897, they dubbed it the "Matterhorn of the Cascades. From Fred Beckey's Cascade Alpine Guide, Volume I

The standard round up is an easy fourth class pitch of a south facing gully. This route takes the more challenging east face. Expect about three pitches of 5th class rock, the second pitch being 5.6.

Suggested gear: 4-5 medium to small nuts, 2-3 cams to 2.5 inches, 60m rope

Activity Notes

Pinnacle Peak (6,562 ft) is located in the Tatoosh range on the southern boundary of Mt. Rainier National Park. The standard climbing route is a 3rd and 4th class scramble up the western portion of the south face. We will be<br> climbing the more challenging east ridge route which starts east of the standard route at the saddle between Castle and Pinnacle Peaks. Team members should be prepared to climb a fixed line on 5.6 rock.  We will descend the standard route.  

We plan to car camp in or near Mt. Rainier National Park Friday and Saturday nights.
