From left to right: Wolf Mountain, Sawtooth Peak #2, Sawtooth Peak #3, and Sawtooth Mountain.
Wolf is Class 3 by the easiest route (there are some Class 5 routes that only a handful have climbed). Sawtooth Mountain is Class 2. Each major Sawtooth Peak appears to be at least Class 4, and any traverse of the group is most definitely going to be a Class 5 affair; I know this from seeing the conditions myself much closer.
