Someone added bolts at the top. As far as I knew the park rangers are against there being bolts and you used to need to tie your webbing to one of the near trees. But the bolts that are there seem to be secure, and who ever added them seemed to have done a good job.
There is also a spire behind the kitchen that is sweet for climbing. There used to be bolts and webbing up there. The webbing was old and torn up and I didnt check to see if the bolts were still there. I solo climbed it today and with a grigri was no problem. There is currently a huge bee hive on the right climb down and toooooooons of poison oak, so remember your tecnu!
FYI That whole are has lots of great bouldering. Bring a crash pad if you want to attempt it because the ground is littered with mini jagged rocks that make landing painful after the first couple.
Any of you that have climbed the Pinnacles know to abuse the useful "rock knocking" technique, and the Kitchen is not a bad place to practice this tactic. I think the rocks are getting looser with age (or people dry tooling haha =P).
