I recently rebolted Pinky Pinnacle, which I reported to Brad and others. This is definitely a somewhat obscure climb although it is somewhat close to the trail. I found bolts and piton holes on it. Despite the climb not showing up in the guidebooks until Rubine's guidebook, I suspect the climb was probably done in the 1970's. The first ascentionists have never been identified.
A close inspection during the rebolting work showed that there are to horizontal piton slots above the first and only lead bolt. This piton slot are unique because they were formed by a Lost Arrow piton for one and probably a knife blade piton for the other. There are no other piton slots above, so I suspect that the first ascent party did two moves of aid then then a few moves of free climbing to the top. Today the climb is a free climb.
Although I have reported this to Brad for inclusion in future guidebooks, I thought I would provide some information on the protection. The piton slot will only accept a deeply placed Black Diamond Red (0.1) X4 Cam, but two lobes will be slightly over-extended. The next larger X4 cam will not fit because the head width is too wide. I do not have a Black Diamond 0.1-0.2 hybrid cam, but if the head width is the same as a 0.1 cam, then this might work better. Please do not try pitons since these would enlarge the slot. The other slot would only take a knife blade, so clean pro could not be used. Because of the so-so cam placement, I used a screamer quickdraw. I now give the protection a PG13+ rating. Do not pull hard on the flake which higher forms a foothold. This flake is loose, which you will notice by the hollow sound.
There are now two bolts at the top with rappel chains. I will sometime go back when El Nino leaves to patch the bolt hole at the bottom. I tried to patch it the day I did the rebolting, but the two part epoxy syringe I purchased at OSH was already solid in the separate tubes. Oh well, I should have questioned why OSH only charged me $0.01 for the epoxy.
