The Class 3 Mountaineers Route (along with a variety of Class 5 multi-pitch routes) begins here at Iceberg Lake, where the North Fork Lone Pine Creek Trail ends. It's a fun scramble up the gulley and couloir to the notch, then a left turn and scramble ascent in the gulley just over the visible north (right-hand side) ridge to the summit - vertically 1900+' total.
