Climbing the South Spur and East Ridge
From Marblemount, drive SR 20 east to the Easy Pass trailhead near milepost 151. Hike over Easy Pass, descend Fisher Creek to about 5,000 feet past Fisher Camp, and climb steep grass and stream crossings to the basin near 6,600 feet below Mesahchie and Katsuk. Follow the south spur toward the east ridge and scramble a maze of ribs and gullies to the east summit, the high point (Class 3 with a few harder steps). Snow lingers in the upper gully into August. Circuit option: add Mesahchie from the shared col. A Northwest Forest Pass is required, and camping needs a North Cascades backcountry permit.
