Cross-posting and slightly modified from the Quest for Mud thread.
Kat and I finished the work at Crowley yesterday (started in December 2018).
All the old bolts were replaced just prior to the 2019 Closures.
Yesterday was spent removing the remaining old anchor bolts.
All the Crowley Towers bolted climbs now have replacement bolts (lead and anchor) and all the old bolts (save one old anchor bolt on Tower Three) have been removed (see the Rebolting Master List). Several of the old climbs have no protection. There are also some new routes out there - check out the Newly Established and Found Routes list.
Of particular interest was one of the old anchor bolts (the right bolt) on Tower One. That bolt was only 1 1/2 inches long and no crowbar was needed for removal. It was a star dryvin but the head on the nail did not overlap the sleeves. Not sure what kind of nail it is but definitely not the correct/stock item. The whole assembly came out after a few taps under it with a tuning fork. Look at the scrunched up lead sleeve on that gem (lower left). For those not familiar with star dryvins - the lead sleeve should be at the bottom of the sleeves and provides all the pull-out strength. It's a miracle this thing did not come loose.
Notice that the right bolt is the top bolt - so all the weight would have gone on it - and it has one of those lovely aluminum lever-out homemade tab hangers. The biner was a leaver that someone put on the lower bolt to keep the rope from getting trapped under the smashlink (Brad?). The picture on the right shows the size of the nail head nicely (it barely overlaps the sleeve edges). At least whoever constructed this anchor placed a second bolt. All the other anchors on the Towers were single bolts. Gotta love it.
