This secluded and remote fin of rock hosts some nice climbing on rock that would be as good as anything else at the City, if it got climbed just a little it more. The slightly less clean nature of the climbing is obviously a byproduct of the approach, because these routes would be very popular by "normal" City approach standards. As it stands, the rock here is indeed good and there are a fine selection of climbs. The natural arch, Lost Horizons Arch, sits in the middle of the formation, but can be difficult to see from above in certain light conditions and from certain angles.
There is a north face that is almost entirely shady with the Checkerboard routes, and tops out on the smaller north summit. I cannot verify any anchor or rappel information for these routes. There is a rappel anchor at the north-west corner of the north summit. You can rappel to the ground with a single 70m rope from here, and a 60m would probably make it as well, but I cannot verify this.
Then there is the west face which remains shady in the morning, but then goes into the sun. The cracks on the far left (north) end of the west face might go in the shade last - especially the left facing corner tucked away. Most of the routes here are on the west face spread out as you proceed down (south along the wall).
