This peak is not in the book. Livingston Douglas added the Southwest Ridge Route found below. Updated December 2019
Peak 10681 is located on the main Lemhi Range Crest between Midway Mountain to the south and The Clapper to the north. Foss Mountain is west of Peak 10681. I climbed the peak in 1981 via the connecting ridge from Foss Mountain. More recently, Larry Prescott climbed the peak on an epic 13-mile, 7,300-foot elevation gain, 6-peak day, which saw him traverse the peak from Midway Mountain to the south all the way to Foss Mountain. This route is detailed in his trip report: Lemhi Enchainment, Little Sister to Foss Mountain. USGS Bell Mountain

West Ridge, Class 2
The ridge from Foss Mountain to Peak 10681 involves some bushwhacking but is straightforward.
Southwest Ridge, Class 2 by Livingston Douglas
Date of Climb: June 29, 2019
The access road for Mud Spring/Cedar Run Creek is located on the Little Lost River Highway, exactly 0.3 miles N of the [signed] Pass Creek Road junction in Clyde and 28.0 miles N of Howe. Turn R/E onto the [unsigned] access road and set your odometer to 0.0. At 0.3 miles, turn R/S after crossing the Little Lost River on a bridge. Cross a cattle guard. At 1.0 miles, turn L/NE at an unsigned road junction. This is Mud Spring Road. At 1.2 miles, go L at an unsigned junction. At 4.1 miles, reach the end of Mud Spring Road in a meadow/cow pasture. Park/camp here (6,900 feet).
From the 9,260-foot connecting saddle with Peak 9634, scramble NNW up a steep scrub/gravel slope to reach Point 9523. Continue along the ridge, heading NNE and descending 70 vertical feet to a minor saddle. From the saddle, climb NNE up a talus/scree slope with scattered pines to reach tree line. Continue up the ridge on loose scree and gravel to reach a juncture with the West Ridge of Peak 10681 at about 10,200 feet.
Scramble E along the ridge, staying on the L/N side of the ridge crest to skirt some rocky outcrops. Drop 70 vertical feet to a final elongated saddle. Climb up loose scree/gravel (using some goat tracks when available) to reach the upper West Ridge. This upper ridge section is a steep, nasty section of ridge outcrops, and sloped ledges/face rock with gravel/scree on them. Be very careful here. This area goes at Class 2+/3 due to the ledge climbing and very loose, steep rock. The slope eases as you near the summit. The summit itself is a gentle hump with ground boulders and a scree base. There is a decent cairn on top.
