As mentioned below, there isn't a bolt at the top. There's a fixed pin on the opposite side but it's not something I personally would lower off of. I was getting ready to bail a stopper and someone yelled to me to use the anchor on the middle finger climb. There are 2 bolts (middle finger anchor) on the wrong face (90 degrees off), that must be threaded.
So your choices are to downclimb (not THAT bad) or clip in direct to the bolts and thread the rope. Bad setup. Like mentioned below you will groundfall from the top and the landing is a bunch of sharp boulders.
It's tempting to climb up this because it's easy and seems so cool to sit atop the middle finger. If your slab downclimbing is solid, it's no problem. Otherwise steer clear.
ONLY CLIMB THIS IF YOU ARE SETTING UP A TR ON MIDDLE FINGER. THIS IS NOT AN ACTUAL CLIMB IN ITSELF.
I couldn't really enjoy this climb that much cause i did it solo. Very stupid choice, Don't do it solo. I got to the top and wanted down right away haha. The downclimb was scary, but could be done very carefully.
