Elevation: 10,985 ft
Climbing and access information for this P2K peak is found on page 297. Livingston Douglas has provided a valuable update that set out below.
Lem Peak is the first peak I climbed in the northern Lemhi Range. It is located above the beautiful Bear Valley Lakes basin. The peak has 2,485 feet of prominence and, as a result, Lem Peak is a popular summit for prominence chasers. At least two prominence chasers have climbed the peak from the west which gave them a higher starting point albeit one with private property issues. Use the link below to read Ryder Irvine’s trip report for the western approach.
If you really want to experience the northern Lemhi Range and bag a bunch of 10ers, backpack into the Bear Valley Lakes for a few days. The photos below are from my 1983 climb. Below you will also find Livingston Douglas’ access update (2017) information and his new route up the peak’s southeast ridge.
Southeast Ridge Route, Class 2, by Livingston Douglas
I climbed this peak on 7/23/2017. From the Bear Valley trailhead (6,800 feet), hike up the trail for about 2-1/2 miles to a junction signed “Buck Lakes 2 Miles.” Here, go left. Hike up this spur trail for about 1-1/2 miles to the point where the trail crosses the outlet stream coming from Buck Lake 8474 on a sturdy log footbridge.
Leave the trail here and bushwhack west up the north side of the drainage to reach Buck Lake 8474. Bushwhack north, then northwest, up a forested shoulder to cross an inlet stream. Now, bushwhack west, following the primary stream up to the north side of Buck Lakes 8920. From here, scramble up the right side of the stream drainage at the base of a talus field. Leave the talus higher up, cross the stream, and climb leftward through the forest to reach a small sub-ridge that is located directly north of Buck Lakes 9456. The bushwhack is now over and the climb begins.
From the sub-ridge above Buck Lakes 9456, follow the sub-ridge west briefly until it turns sharply south. Continue up the talus-and-boulder sub-ridge as it climbs steeply south to join the northeast spur ridge at 10,300 feet. Scramble up this less-steep spur ridge southwest to Point 10460 on the southeast ridge of Lem Peak. Don’t be tempted to contour around the north side of Point 10460 as the terrain is steep, loose scree.
From the top of gentle Point 10460, descend west-northwest approximately 60 feet to a narrow saddle. From here, climb northwest up the ridge on Class 2 ridge rock. You’ll soon be on top of the small ridge crest that is Lem Peak’s summit. Congratulations, you’ve reached the top of the crown jewel of the Northern Lemhi Range! Enjoy the views!
If you plan to also climb Buck Lakes Peak (as I did), descend the full length of the southeast ridge of Lem Peak to a gentle ridge saddle at 10,100 feet. If you stay on the ridge crest (climbing up over Point 10460), it will be a Class 2 climb the entire way.
