Bear Mountain sits west of the main Lemhi crest and south of Iron Creek Point. Its position “out in the valley” makes it great view mountain with a superior 360 degree vista. The book contains one route which begins at the saddle between Bear and Iron Creek Point. Down the page you will find route information for a traverse from Peak 10112 and for climbing the peak’s south face.
Bear Mountain from the northwest.
Bear Mountain/Peak 10112 (Little Bear Peak) Ridge Traverse. (Class 2-3)
The ridge line between Bear Mountain and Peak 10112 is an enjoyable section of Lemhi Range terrain. I crossed it when it was mostly covered by snow. The ridge has two low spots which are closer to Peak 10112 than Bear Mountain. . The eastern end of Bear’s summit ridge is the most challenging section of the traverse as it is as close to knife edged as you can get without significant exposure. With the snow gone this section of the ridge might have a couple of Class 3 sections. If covered with snow you will want an ice axe.
South Face Routes. (Class 2)
Bear Mountain’s broad south face offers a number of feasible lines which are reached from Summerhouse Canyon. Summerhouse Canyon. The road is passable to high clearance vehicles when dry although I recommend a 4WD with good tires as the road is rocky. There is a good parking spot at 7,400 feet. The middle rib provides the most direct line to the top. Access from the Lost River (dirt) Highway is found roughly 2.2 miles north of the Summit Creek CG, turn right onto the Summerhouse Canyon road and follow it toward the mountains for Another 1.25 miles to an intersection. Turn right, cross a ditch and then turn left. Follow this road as far as you can get into Summerhouse Canyon.
The GPS track below shows the line I descended and the photo show other possible lines. The lower sections of the face are forested and the upper sections are talus without any significant obstacles.
