East Face, Class 3
From the Alturas Creek Trailhead, hike up Alpine Creek gaining only about 800 feet in the first 3 miles. Leave the trail at this point and cross the creek. Climb up a trail-less drainage shown on the map. Climb to Lake 8650 and then up the grassy slope to the left of the lake to the ridge top. Mattingly Peak and Peak 9860 are now visible (see photo). John Platt reports “Peak 9860, located on the climbers’ right, is more dramatic, but a bit lower.” Traverse under Peak 9860, following a less-steep band under the upper mountain but above the cliffs that drop down to the lake. The final climb to the summit is a Class 3 scramble. Use the link below to read John’s trip report.
