About Rainbow Slab(OS):
| Please do not climb on the tier below Rainbow Slab, it could result in a total ban in the quarries. The slab is located on your left as you approach, about 150 feet high and 200 feet across. By far the best looking slab in the area, with about 20 routes, though most are quite interesting and exciting, and graded as such. |
