I think this is a photo of the Grand Specimen. It even has a sign at the base of the rock that says so. The approach is a real grunt, as there is no obvious trail. Expect about a 1 to 2 hour uphill bushwhack. This is a very atmospheric place with lots of falcons flying about. In R&I 95 there is a good mini-guide by Stewart Green that includes the Grand Specimen, showing at least one route that goes up the center. It is called the Directissima (III 5.10c). Dan St. John and I climbed an obvious line on the left side of the cliff a few years back, up a dihedral system, but I think there was evidence of previous climbing on the route. So, I expect that most of these lines got soloed in a pair of hush-puppies back in the day. Grand Specimen may also subject to a seasonal raptor nesting closure.
