Our latest adventure. Doodlin' Dody.
The normal approach is completely choked out with Poison Oak.
Here is a picture taken from below Casino Rock, just past the switchback near the Don Genaro waterfall overlook.

Here is a photo topo made from zooming in on the previous picture. You can see the drill dust from the bolt replacements.

Disclaimer and warning - it looks like the pinnacle is not that tall.
This is a very tall pinnacle. A major portion of the downhill side is obscured by the nature of this downhill view and the brush. When you start down the notch on a skinny fin to gain easier access to the slab, the exposure is immediate.
Above the first bulge, a crumbly-looking stance gets you to a fixed stopper in a small slot.
Someone evidently fixed this piece and bailed, leaving an oval carabiner on it - likely years ago when they couldn't find the bolts or possibly freaked out from the rock quality.

Unfortunately I did not have a nut tool, so I gave the stopper a good yank and it was fixed solid. It was a small nut turned sideways - maybe 5 or 6? on the BD scale (I should have taken a picture) and the wire was thinner than any nut I own. There wasn't enough room in the slot to place anything else, so I said Vaya con Dios (no one actually says that) and clipped the piece with a long runner. I had also clipped my yellow alien with a long runner. Moving out to the next stance completed the zag in my zig-zag and I was now set up for the hopeless rope drag. I don't think 4 foot runners would have made a difference. Maybe 6 or 8 foot runners. I have to wonder if the first ascent party didn't belay from the first bolt - that would absolutely work.
Kat had been asking me the whole time if I saw any bolts.
Here is the most current route description: Move up and left past 2 bolts and over 2 bulges. It is possible to use small gear to supplement the bolts. The summit anchor is very old.
Well...that was 2 bulges so far and no bolts. When I got to the next stance, I saw the 2 old bolts - 4 feet apart on the final, filthy, lichen-covered, loose slab. Sounds exciting huh?

That second bolt was clearly placed by hanging on the first one.
I clipped the first old bolt and stepped up. You would think I would know better and would have pulled more slack into the system. The rope drag was so bad I almost didn't make it to the 2nd bolt (4 feet away).
I struggled past the second bolt screaming for slack the whole time (what a maroon!) - Kat kept yelling back that I had slack. One more dicey pull to get enough slack to move and I made it to a rest stance. From there I pulled out more slack to make the final run to the top. When I got to the top, I told Kat " that was harder than a sustained 10a!" In retrospect I should have just pulled out 20 feet of slack before trying to climb past the bolts.
Once at the summit, I rested a bit before starting the chore of replacing the anchor.
When the anchor was done, I belayed Kat up and then rapped down and replaced both lead bolts in their original holes.
The second lead bolt came out with my fingers after applying the tuning fork

Here's the old anchor. (I left it for the sake of history)

The new anchor.

The replaced lead bolts - close enough to be photographed together while hanging from the rope
