Etude For The Left Hand 

I was here a couple of weeks ago. I took a look, and I can't even tell if there's been bolts installed period. Fun climb though. If you feel comfortable with the right side, definitely try this (enter the slab from the boulder you use to get up on the relatively flat "lunch time" rock, not from the right). Good practice for Drop Zone on the fall wall.

Yep. I couldn't find any evidence of bolts there either. I just toproped it after having led Cornelious on the opposite side of the formation. There is good pro in that crack and from the top its an easy walk to the anchors.

The only evidence i could find of bolts was some empty hangers on the rock. Somebody must have removed the bolts

If the route is still in the condition it was in last year, then the bolts are there but the hangers are gone. There are only two or three bolts. If you want to lead it you can take a nut and slide the actual nut down it's cable, exposing a loop of cable above the nut. Hook the bolt with this loop of cable and then slide the nut up snug against the bolt. A little sketchy but it does work, and I do recommend you try this a few times on the ground before venturing up. Slide the nuts so they are ready to "place" before leaving the ground. A better option for a climb to lead at a similar grade that requires only draws would be Southwest Friction on Poland Hill.

Someone bolted this route. It's scheduled to be chopped. It has been accepted as a TR and doesn't need some punk wannabe never will be bolting it.
