North Ridge

This ascends a slab with a flake system to balancy undercling traverse to dihedral ramp with large blocks in the corner.

Hike Thunder Lake Trail to Lake of Many Winds, then scramble up the slabs and ramps to gain the ridge crest above (possibly low 5th Class). From here (Boulder Grand Pass), hike south toward The Cleaver, and traverse around its east side. South of The Cleaver, follow the large ledge around to the western side of the ridge, and reach the base of the technical climb(s) which provide access to the North Ridge proper.

An alpine rack.
