Just below the crux on Tensile Strength.


Tensile Strength climbs the line of old quarter inch bolts right of Pins. The first 3/4 of the climb is fun, fairly easy climbing. Climb a thin crack to a flake that trends up and left. Follow the sloping holds along the flake until you can pull up and stand on top of it. The crux is the blank section above. Strenuous moves on small nubbins and edges lead to the top.


It lies about eight feet right of Pins, just left of an angling, left-facing corner at ground level.


Various anchors located along the top of the wall.

Them bolts were placed by homo habilis. Clip them, but treat this as a gear lead.

The 4 bolts on this route are mostly old buttonhead hammer-ins, which are rusty and not to be trusted. They need to be replaced with modern stainless steel wedge bolts or glue-ins.
Also, the crux of the route (at/moving past the last bolt) is more like 5.10+/11- if you stay direct on the small crimps and technical foot moves.

The bolts are 5/16" buttons placed by me around '88. The route gets a Quarry rating of 9+.

We climbed this route on 04/05/2014, and there were shiny new bolts, and plenty of them. It is now very well protected and a fun lead.

Who took it upon themselves to change the climb and the experience for everyone? I agree with replacing bolts but not adding new ones and putting them in different places! This has completely changed the climb and robbed myself and everyone else of one of the better climbs in QQ. If people are scared to lead it because it is a little spicy, they should top rope. Donít dumb down a climb used by many down to your level. Just because you and your buddies are scared or are not climbing strong enough does not give you the right! This is not Rumney, this is QQ, 5.9+ is a 5.9+ and a 4 bolt route has 4 bolts. Donít rob us of real climbing so you can feel better about yourself. Go elsewhere please!

Chris Kreutzer, there is literally nothing stopping you from skipping the new bolts.

What a BS statement!! Why not bolt everything...everywhere.... The route was fine for 25 years with the number of bolts on it and now it's not?

John is right ó the route should have been left alone. Or, if the old bolts were unsafe, the new bolts should have been placed where the old ones were; otherwise, you're changing the style and nature of the route. If someone wanted to add more bolts for some reason, he or she should have talked to the first ascensionist before they moved forward and did anything to the climb. The Quarries might look like hell (especially with the multi-layers of new paint that have been added in the past twenty years), but it is one of THE classic areas with a storied history.

I enjoyed the new bolts, well done. Thank you.
PS. I have never seen any one lead with the old bolts.

I for one am thrilled that there are new bolts on this climb. The old bolts were 25 yrs old! In a spot as well traveled as The Quarries, safety should be of utmost importance. Much time and effort has been put into keeping access of QQ open to climbers, and people decking off this climb is only going to hinder that. The previous spacing of bolts was beyond spicy and just plain dangerous, possibly due to the climb changing after the big dig fill in (after the climb was bolted in '88). The "it ruins the aesthetic and nature of the climb" is complete bs considering the route has been smothered in graffiti and gallons of spilt paint in the past few years. The Quarries is a training ground, pure and simple. This is not a pristine destination area. A few bolts isn't going to hurt anyone.

Beyond spicy? Dangerous? Really, you need to get around more...the climb was led hundreds of times with the existing bolts and falls were taken.

Please don't lecture on Quarries access, I was one of the people fundamental in keeping the place open in the '80s.

My first time leading Tensile Strength I was uneasy about pulling up clipping slack for the second bolt. Strongly believing no one climb is worth getting injured over, I ultimately decided to hang on to the quickdraw while clipping. I was not happy about pulling on gear, but I did not go out there with my hammer drill and place new bolts. After a little problem solving, I went back a few days later with a new strategy. I decided to clip the second bolt with a double length sling that had already been clipped to my lead rope before I left the safety of the first bolt. This eliminated the need to pull up slack when clipping my lead rope to the second bolt. I could then pull up clipping slack, without risking a potential groundfall, to clip in to a standard length quickdraw on the second bolt. Call me a chicken if you will, but I have used this trick probably a half dozen times over the years when I felt that falling with clipping slack out would put me in unnecessary danger. Had it not been for the way Tensile Strength was originally bolted, I would never have developed this trick to keep me as safe as I can. For me, Tensile Strength was the epitome of a training ground as it pushed me to develop my climbing, climbing strategies, and awareness of danger. I am sorry to see that future climbers will not be challenged to develop there climbing as I was.

"I am sorry to see that future climbers will not be challenged."

Pretty easy solution to the problem. Remove and patch. The color match should be easy, just bring some spray paint. If you let this behavior stand at your crag, it becomes precedence. Speak softly and carry a large wrench.
