Ambush Peak, Dike Route. Ambush Peak’s main face rises from a low angle apron, becoming steeper at mid-height, and is capped by large overhangs near the top. The northeast face is devoid of large overhangs, but rises at a constant angle, ending sharply at the true summit. On the extreme right side of the northeast face is a black basaltic dike that divides the main face and the shorter north buttress to the right: the site of two established routes done in the early 70’s. In August, my father, Stephen, and I climbed a new 12-pitch route (IV 5.8) that ascends the granite just right of the basaltic dike. At times we were stemming between granite and basalt. The route gradually steepens, entering a wide crack system, and 400' below the summit we followed solid rock to the right, up a steep crack system.
