We climbed Gillette Arete on Saturday. Since Pete and Tim's ascent in 2009, there was only one other entry in the register from 2013.
The position and the climbing are excellent and very unique for Oregon. The approach is long, and the route is really only two pitches, but the Muddy Fork of the Sandy is a beautiful place, and the hike was well worth it.
We approached up the north side of the south branch of the Muddy Fork, which required some bushwhacking through slide alder and scrambling up and down the banks of the river. The south side of the river looked friendlier, but there was a lot of water and we weren't too stoked on a creek crossing higher up in the drainage.
I'd say the first pitch goes at 5.8 with a short crux through a roof with a tight hands crack. The second pitch felt like 5.10a - a really nice tight hands face crack eventually leading to the summit. The entire route is out on the edge of the formation with excellent exposure, solid rock and great views of the Sandy River basin. And from the summit, you can take in really pretty vistas of the West Side of Mt. Hood and the Sandy Glacier Headwall. It's a cool spot for sure and worth a visit.
