This has continuously fun moves on good solid rock that's not too sharp. There is pro by the hard moves, but there are some runouts on easier ground. At the top, there is a section where there are some non-trivial, harder if you are shorter than 5'6", moves above and around the corner from the 7th bolt.

It is easy for the grade, the crux is at the 2nd bolt.


On the far right side of Spiney Ridge, just before you turn the corner and it becomes the New Gym, there is a concentration of routes. The most prominent of these is Corrugation Corner and obvious offwidth / chimney which is (thankfully) unbolted. Cornerstone is two bolted routes left of this.


8 bolts.

Get on it!!! This route has incredible movement, perfect holds, and a beautiful location. The bolts are slightly runout, but all of the hard moves are well protected and the clips are made from great stances, so it doesn't feel too spooky. Classic!

This is a good route but run out and has a large loose flake at the top. Be careful at the last bolt to anchors. It is fun, so if climbing at the grade, get on it.

I thought the route was super fun and safe. The very bottom section getting onto the beautiful face was more tiring that I had expected. Okay rest near the end of the crux section then a few no hands rests on the easier top section (there is one more heady crux near the top, but not too bad). A good route to onsight and a lot of fun!
