McNutt Peak (Peak 10327)

Elevation: 10,327 ft
Prominence: 507

Climbing and access information for this peak is found on page 296.


McNutt Peak/Peak 10327 is the northernmost Lemhi summit to climb above 10,000 feet. There is good access to this peak and four other Lemhi 10ers via the Bear Valley Lakes Trail, (A)(10.2)(a). Livingston Douglas has provided an alternative and more detailed route description than the one found in the book.


South Ridge Route, Class 2+ by Livingston Douglas

I climbed McNutt Peak on 7/21/17. I used the Bear Valley Lakes Trail to the northernmost Bear Valley Lake. However, my ascent differs from the standard “climb north from the upper lake to the summit ridge.” The standard climb requires scrambling to get to the summit ridge and actually puts you on the east spur of the summit’s South Ridge. Instead, from the highest lake, continue along and up a trail that switchbacks steeply to the west and ends on the ridge saddle at 9,820 feet, directly south of McNutt Peak.

The trail from the highest lake up to the saddle is NOT shown on the Lem Peak Quadrangle and was both unexpected and welcome. The trail was free of snow when I hiked it. This was surprising given its east-facing exposure and forested nature at a time when there were sizable snowfields lingering elsewhere in this area.

From the 9,820-foot saddle, follow the ridge north (staying to the west side of the ridge crest as necessary). Continue upward through scree, rocky ridge outcrops, and krummholz. The ridge steepness eases and the krummholz disappears around 10,200 feet. From here, you have a Class 2 talus hop to the summit. Skirt or climb over a false summit and two more ridge humps en route to the true summit, which lies at the north end of ridge “plateau.”
