"Although I didn't get a chance to check it out, there's good potential for a nice traverse from the north summit to the central summit. Check it out!"
I gave this a shot, but got stopped at a 20-foot dropoff along the way, about midway. Definitely class 5.too-hard-for-me. Ended up dropping down the east side, but good, fun scrambling nonetheless.
From the notch between the south and main summit, there is an obvious chimney. It's to the right of the slabs everyone else describes and begins above the highest point in the notch. It looked easy, so I tried it. Zero exposure and it took me right to the top where the register is. Felt like class 3, but that is always debatable.
