From the 10,000’ divide on the boundary of the Teton Wilderness. The summit of Breccia Peak is NOT visible here. Follow the ridgeline past Point 10,315 (Class 4 scramble on that if you feel like it); either side of the ridge works, but the right side is easier, in my opinion. From the notch on the other side of Point 10,315, ascend the ridge (Class 2 if you stay just beneath it and Class 3, and much more fun, if you stay atop it) to the gully system (visible here) just left of the sheer cliffs to reach the gentle tundra slopes above. The gullies section is the crux of the route because it is disgustingly loose and very steep, but the difficulties there are only Class 2+/3.
