Pinnacle Ridge Guidebook


This many-summited mountain sits on the Divide between Gannett and Woodrow Wilson and is most conspicuous when viewed from camp near the terminus of the Glacier Trail. It is likely only climbed by dedicated peakbaggers or those seeking obscure technical challenges.

General Considerations

Despite its somewhat uninspiring stature, Pinnacle Ridge would make a worthwhile objective for those with extra time before or after climbing Gannett. The author combined these peaks by using Gannett’s southeast couloir (Route 2). Notably, the glaciers around Pinnacle Ridge are much more crevassed than in many other parts of the Wind Rivers.

Route 1: East Couloir – Class 4, Moderate Snow

The first step to approach Pinnacle Ridge is to reach the top of the arm of the Dinwoody Glacier just east of the summit. Coming from the Glacier Trail side, enter the region as for Gannett, then stay north along the edge of the Dinwoody Glacier’s northernmost arm instead of gaining the “upper bench” on Gannett.

Another option would be to climb over Glacier Pass, the col between Pinnacle Ridge and Gannett Peak, starting from the vicinity of Mammoth Glacier. No matter how you approach Pinnacle Ridge, plan on crossing significant crevasses and regions of bare ice as you navigate the glacier.

From the broad swath of the Dinwoody Glacier extending to 13,000 feet, follow a snow hogsback to the center of Pinnacle’s east face below the highest (central) summit. An obvious short couloir leads to the ridge crest, where a short west-side excursion on loose rock leads steeply south to the summit boulder. Mounting the highest boulder is the crux, with a couple moves of exposed 4th class.
