Cutthroat Peak/Southeast Buttress

A Grade III, 5.8 rock climb in the North Cascades near Washington Pass.

getting there

Drive I-5 to Exit 232 (Cook Road) at Burlington. Turn east to Sedro Wooley and junction of SR 20. Turn left and drive through Marblemount (47 mi) and on to Rainy Pass. Continue east about three more miles and park along highway near Whistler Mountain sign.


Descend from highway to crossing of State Creek. Ascend open slopes on east side of southeast draining stream to basin immediately south of Cutthroat Peak.


Ascend to basin headwall and climb twin gullies to notch at base of Southeast Buttress. Start in right gully and traverse into left gully before notch. Above notch, easy scrambling leads to short, steep face. Stay generally near crest of buttress, then follow large ledge to the left. This leads to a gully that must be ascended to “Tarzan Jump” at its top. Scramble sandy gully above to notch between the false summit humps, then climb mixed 3rd, 4th and 5th class rock to summit.


Rappel and downclimb route or the West Ridge (reportedly loose rock and high potential for rockfall).
