Well, the Lopez crag is just like Erie only undeveloped and slated to stay that way as it is under the auspices of the BLM as one of their ACEC (Area of Critical Environmental Concern)basically their Wilderness designation.
There are some boulders, cracks and all of the cliffs are somewhat top ropeable. We climb there but don't expect bolts and permanent anchors. The view is great but bring your helmet.
