Thanks for the heads up, Jimbo.
The bolts at Big Shadow are increasingly worse, to the point where all routes need to be re-bolted indeed. Many of those bolts are by the now-defunct Greek manufacturer Rockland, whose materials proved to be downright problematic.
Big Shadow has been on the list of sectors to be re-bolted; however, the recent re-bolting program only covered 300 routes and other, more popular sectors routinely visited by thousands of climbers had to be prioritized. We are hoping to re-bolt Big Shadow in the near future, either voluntarily or within the context of an official maintenance program.
We will advise climbers not to climb at Big Shadow until further notice.
