Pinnacles Peak

Elevation: 9,273 ft
Prominence: 1,253

Two climbing routes for this peak are found on page 121. John Platt climbed this seldom visited peak in 2019. His trip report is linked below. Updated August 2019


This peak stands out from its neighbors with a rugged summit block, steep towers trending north from the summit and 1,200 feet of prominence,.I’ve climbed it twice and recommend it as an outstanding climb. However, I suspect that the trail for the Missouri Ridge Route has deteriorated since my last ascent in 1995. I do not believe that any of the lower pinnacles have been climbed.

Access

The book lists two routes. Both utilize the Missouri Creek Drainage. You can either follow the drainage to the base of the peak or the old Missouri Ridge trail.

Missouri Ridge. Take the Missouri Creek trail up the valley until you reach a cabin. From this point, an old Trail proceeds to the top of the Missouri Ridge north of the peak. From saddle between Missouri Ridge and The Pink, turn north and proceed up the ridge to the summit block. Surmount, the summit block on it’s east side. The trail was in poor shape years ago. Originally a four-wheel-drive Road or logging road find plenty of downed trees on the route. Class 3. USGS Edwardsburg

The Forest Service no longer shows the trail from the creek bottom to the ridge as a maintained trail. However, the boundary for the Frank Church River of No Return Wilderness excludes the trail corridor from the wilderness. Thus, this map gives you a good idea of where the trail runs. John Platt reports “We were able to fish a card out of the Pinnacles Peak register from a family that had used the Missouri ridge trail to fish the lakes on the other side. So I think the trail from the cabin is probably okay.”

Missouri Ridge Is on the left and The Pinnacles on the right in this Google Earth image. The old trail ascends to the intervening saddle from Missouri creek which is the drainage behind Missouri Ridge.
