| Although it is named Centipede in the guidebook, it was named Clicking Barnacles by the FA team. Many of the corroded looking 1/2" 5 piece bolts used at Promontory and other Redwood Coast crags tend to be in better shape than they appear. Attempts at chopping them in order to replace them with titanium glue-ins proved to be very difficult. The threads were rusted enough to prevent unscrewing and all efforts to "pull" the bolts resulted in failure of the surrounding rock rather than the bolt. When I ground the heads off some of these bolts they generally had a veneer of rust covering solid metal. Still, it is recommended to climb within your limits on the coastal sandstone so as not to press your luck too much. |
