Elevation: 8,150 ft
This peak is not in the book. Livingston Douglas provided the alternative access and new route information found below. Updated November 2019.
Peak 8150 is located east of Moore, Idaho, on the north end of a moderate ridge that runs south from its summit to Arco Peak and ends just east of Arco, Idaho. The ridge parallels US-93. USGS Arco North
Access the peak from the King Peak Launch Site Road [(B)(17) on Page 293]. Follow the road until it switchbacks back to the north. From this point, keep right and continue on to Beaverland Pass.
Northeast Ridge, Class 2
From the pass, a 4WD road leads up toward the summit. In fact, the road leads almost to the summit. Park at least 1,000 feet below the summit and enjoy the nice walk. You can easily climb Peak 8082 from the summit of this peak by hiking 1.0 miles to the south and crossing the connecting saddle.
East Slopes Route, Class 2
Steve and Margo Mandella climbed these peaks in May 2018. They approached the peak from the south via the Arco Pass Road [(B)(18) on Page 293]. Because of a heavy rain event earlier that year, the approach roads were severely washed out in places and they were not able to drive all the way to Beaverland Pass with their high-clearance 4WD vehicle. Thus, they accessed the peak from Beaverland Pass Road on the northeast side between the two mountains. See the track below for their loop route. Their trip stats for the loop route: 4.93 miles with 1,906 feet of elevation gain.
West Ridge, Class 3 by Livingston Douglas
From US-93 in the center of Moore, ID, turn right/east onto 3350W (signed for “King Launch Site”) and drive 100 feet. Turn right/east onto [signed] 3175N. Drive 2.0 miles east on 3175N to its end at a signed “T” junction (King Mountain Road). Turn right/south and drive 0.2 mile to an unsigned junction with a rugged jeep road heading east. Park at the base of this road at a cattle gate (5,495 feet).
Go through the cattle gate and hike briefly up the 2-track jeep road. Scramble cross-country across easy scrub to quickly reach the base of the west ridge after crossing a minor gully. Climb the steep west ridge, staying near its crest. The first 850 vertical feet is steep and rocky and has large blocks, rocky buttresses and steep face rock (e.g., ledges). This is a challenging Class 3 ridge scramble. Angle diagonally up to the right to skirt sheer cliff face sections. When viewed from the bottom of the ridge, it looks like this ridge is probably impassable but, surprisingly, it goes.
The mid-section of the west ridge is easy Class 2 scrambling on open scrub with a scree base. Higher up, you can skirt any ridge outcrop problems by generally going around the left/north side of the obstruction(s). Finish the climb on an easy open tundra slope. The summit is a rocky, narrow ridge crest. There are three cairns on the summit. The middle one is probably the highest and has a stick in it. Stand on all three just to be sure you hit the high point.
Southeast Ridge, Class 2
Same as for the west ridge
From the rocky summit area, descend the easy, open terrain (short scrub and broken scree) southeast to a saddle. This goes quickly and is an easy Class 2 scramble.
