I found this crag a disappointment as most climbs are over after ten or fifteen feet. Momentum Operator on Broken Rock, along the approach, seemed much more worthwhile. Jun 16, 2007

T, the route with fixed nuts/pins is an existing climb rated 12a. I forget which guide I saw it in. It would be more friendly if the gear were "updated", but the FAs would need to do that. Jun 5, 2006

Is the line up on the Overlook with the fixed nuts and pins a project, an open project, or an existing climb? Jun 5, 2006
