This is the obvious overhang / arete combo. It starts with a pretty tough sit start underneath the roof that's kind of a roof. It starts with a small pocket crimp on the right hand and a small sloper under the roof on the left. The start is definitely the crux. Once you manage to get out from under the roof without putting a foot down then it's just a few moderate moves up the arete to the top.
This route is located on the boulders farthest upstream and it's on the left most boulder in this area. It's pretty obvious.
Pad and spotter to keep you from rolling downhill.
