A few different people warned me how crappy this crag was. Today I decided to see for myself.... While it is true that lots of the rock up here is like a rotten road cut, this route on the other hand was great. It is one of the best kept secrets in Boulder Canyon! Normally I wouldn't support the addition of 9 retro-bolts, but this route is great fun in its current condition. Hopefully it was bolted by the FA or at least with his permission? I would certainly recommend this to a beginner leader. The well-protected crux is at the first roof and didn't feel much harder than 5.7. The guidebooks give this a 5.9 rating, but you'd have to try really hard to make it feel that difficult.
The somewhat long approach (by Boulder Canyon standards) and the lack of other easy sport routes will probably doom this route to obscurity. But if you are looking for an easy sport route with a nice flat base, well-featured, and well-protected rock in a remote peaceful spot, this could be the route your looking for? The views of Castle Rock alone justify the hike....
This is the bolt line on the left face of the giant open book at the right side of the Left Mountain Rose crag.
9 bolts and anchor.
