Description Suggest change

About 25 feet tall, the Main Formation has a handful of pocketed face climbs as well as a noticeable crack on the left side, and a strange ramp on the right.

This rock has a large solid metal pole set 15 - 20' behind the main face of the rock, which allows you to use long slings to setup top ropes on the 8 or so climbs (5.6 - 5.11d) on the face. Be sure to bring long slings (~25') to this rock, as the top edge is quite sharp, and you want to ensure that your top anchor sits all the way over the edge to reduce / eliminate rope drag.

There are also two nice shiny big bolts closer to the edge for setting up a top rope, avoiding the semi-sketchy metal pole setup. 

Getting There Suggest change

This is the large face left of formation with the plaque on it. It has a picnic table directly in front and is clearly visible when you first park.
