In reply to: If you cannot tell the difference between a safe fall and a dangerous one, then I don’t know what to say. (Yes, I do. If you weren’t able to tell the difference, you would not still be here.) You don't alway control your fall. You don't alway know how or were you going to stop or land. Climbing sometimes is a "leap of faith". I trust that bolt, nut, friend, sling, quickdraw, belayer or anchor to hold my fall. Doesn't alway happen. I have been on and done (r and x rated) routes that if you fall you could hurt yourself or even die. In that situation the gear becomes secondary and your ability and experience comes first. I'll stick with my views and you to yours.

If I shifted the webbing 6" to the left I'd ride it on TR. Like the quadrupple fishermans...nice touch.

In reply to: You don't alway control your fall. You don't alway know how or were you going to stop or land. For the most part on a sport climb I do know where and how I am going to land. The times I have been injured due to misjudging this are pretty rare. Maybe 4 times in twenty years, and the worst it ever amounted to was limping for a couple of weeks.
In reply to: Climbing sometimes is a "leap of faith". I trust that bolt, nut, friend, sling, quickdraw, belayer or anchor to hold my fall. Doesn't alway happen. That is exactly why you back things up.
In reply to: I have been on and done (r and x rated) routes that if you fall you could hurt yourself or even die. In that situation the gear becomes secondary and your ability and experience comes first. In that situation a rope becomes largely superfluous. I prefer to forgo the rope and the constant wondering of “is it alright to fall or isn’t it?”
In reply to: I'll stick with my views and you to yours. That sounds good, as long as your views do not effect my safety.

In 34 years of climbing hard routes I have never been hurt from falling. So who is safer? Or maybe I am just smarter than you! You can't alway back up gear on a lead climb that is rated r or x. There is lack of good protection or none at all, thus the rating. On a r or x rated route it is never alright to fall at the r or x rated part of the climb. My views or opinions have nothing or very little to do with your safety. Not much more to add. Let's move on...

Curt, Quick question. Since everything but what we see in the photos is conjecture, let me ask this: is there any situation where this anchor would not be adequate? For instance, if I told you the route below the anchor wandered 20' left and right of the anchor. Or if a group of schoolchildren would be toproping on it all day. Or perhaps if I told everyone I knew that Curt Shannon tied quadruple fisherman's knots. Let me ask you a slighty different question. If you were building the TR anchor for that spot, how would you do it? FWIW I wouldn't setup that anchor. I might climb on it,depending on a lot of factors. Wouldn't put my kids on it. Murf

Murf I said earlier that I was done with this thread. However, since you are addressing your question specifically to me, I will answer. If the route "wandered 20' left and right of the anchor" that would cause me to be even more concerned with the lowest sling running across the rock edge--since a sideways pull on the anchor would amplify the chances of that sling cutting over the edge. The answer to that potential problem, however, is not to double or triple-up on the slings that would be potentially sawing back and forth across the rock--but rather to fix this problem, by perhaps moving the anchor, immobilizing the slings at the lip, or padding the lip. If I were building this anchor, it probably would not look exactly like that. But, I do not know exactly what the constraints were that the person building this anchor were. Maybe nylon is tied to nylon here because the person who set this up did not have any more carabiners with him? Maybe those were the only three stoppers the guy owned--who knows? Anyway, the main question seems to be whether this anchor is safe enough. I think absolutes are hard to come by. So, when you ask me if I would climb on that anchor or let my child climb on that anchor, I can only say that the answer is "yes" based on what I can determine from the pictures that we have. Curt

I'm afraid I fall into Dan's camp on this one, at least in terms of doubling that sling. I prefer redundancy if possible. Is is, however, much like everything in climbing, a personal choice.

One last comment. There are “generational” differences in safety practices and perceptions. I am pretty sure that some of the things that I do would seem unsafe to many of you. Curt Bob Clyde Have all stood the test of time and are surely among the safest and most knowledgeable people on this site. I would ask that if we ever do happen to rope up, that they would humor me in this respect. d.

Plase don;t bend over for hte old guys who somehow managed to stay alive while doing things that are suspect. I've seen famed and semi famed as well as plain vanilla long time climbers do STUPID things, things they had been doing for years, and then get testy about it when they were called on the poor technique. Not going to name names, but such things as linking biners together to extend a sling, belaying off a dead tree when a live one was 5 steps away, placing newfangled gear( cams) so poorly that they rattled out of hte placement, joining rappel ropes together wiht the death 8, using a snort rope to lower off a long climb, and more. I've climbed up to a belay and heard, " You're not going to like this, but hey I never weight my belays anyway.". Old dogs need to learn new tricks. DOing something poorly for a long time and getting away with it does not make it a good practice.

Good points, dirtineye. As for longtime climbers being themselves "proofs" of their safe ways, seems to me to be a flawed argument. (Note, it seems to me, not saying that it is.) Maybe we should go on and discuss the "Anthropic Principle"...?! :)

In reply to: DOing something poorly for a long time and getting away with it does not make it a good practice. This is totally true. My point is that their practices are not likely to kill them, and as long as I do not adopt those practices, then they are even less likely to harm me.. I don't see this as giving in, but more of a live and let live. I to have climbed with Famous 30+ years climbers that are great people but I would never ever rope up with them again. Curt is not one of those people and odds are neither are Bob and Clyde.

So... I was looking up "pissing match" in an online dictionary and it didn't offer a definition, but rather a link to this thread. And that's how I found myself here, again.
In reply to: Odds are they put an overhand loop on the rope/biner end of the webbing (not shown but the orange sling has one for the same reason) so even if one strand was cut through (exceedingly unlikely, even without the padding, given the nature of 1" tubular), the other would still hold a TR fall. The thing of interest is did find was the above. The sling (farily certain it's not webbing) is girth hitched to the cordellet. Even if there was a knot near the at the rope end, would the girth hitch be a sufficient knot if one strand of the sling is cut? And that is a real question. Assuming the maximum TR force is something near a 1000 lbs. Any thoughts?

It is not redundant.

The most interesting thing to me is that some people actually give the anchor builder the "benefit of the doubt". This anchor, although many people would actually use it, shows so many signs of being a "beginner" construction that it makes me question even the things that seem adequate. It is way overbuilt in some ways and strikingly lacking in others. I'm not going to go into each example. An overhand knot in the sling down by the TR biner would not surprise me at all; another thing added because the builder thought it was safer but actually a useless feature.

When I wrote out those "rules" in the two anchor books, the idea was to establish a general and far-reaching protocol that would maximize the likelihood of folks building anchors that would not fail. Over a very short time the rules got codified into a sort of gospel – not strictly my own, since I drew upon many sources, and after standardizing the terms, wove the lot into one overall strategy. Perhaps the result saved a few lives. Anyway, the downside of this "gospel" is two fold: first, folks came to believe that if the anchor met the SRENE (solid, redundant, equalized, and no extension) criteria, said anchor was automatically fail safe; and second, any anchor that did not meet the criteria was, without exception, a liability, as was the climber who placed same. Reality does not support either notion. There are far too many accounts of well rigged anchors that failed for the simple reason that SRENE criteria cannot compensate for bad, primary placements (bombproof placements remain the backbone of all sound anchors). A case of the second false notion was played out one time at Trashcan Rock out at Joshua. Someone complained that the top rope anchor was not perfectly SRENE and therefore the anchor was, by definition, suicidal. I informed the guy that he or anyone else was invited to try pull that anchor out and they never would. The guy went so far as lash the static TR rope to the bumper of his VW Bug. His tires spun furiously in the gravel but the anchor held fast. The "proof" of that anchor's robustness was that even a car couldn't yank the anchor apart. And yet the poor fellow was still displeased. Clearly, he adhered to the kind of fundamentalist thinking that believed a standardized protocol would automatically make all anchors acceptable, and that any breech of the code spelled death or bad judgement, this despite a working example–of his own making–which showed him otherwise. He simply could never differentiate between a definition on paper, and what actually played out in the real world. Mind you, I'm not knocking my own protocol, or suggesting that you rig a top rope anchor off a single strand of anything (for anyone wondering, I almost always rig a TR off a bight of static line–2 strands–with the anchor point consisting of two lockers connected to a Figure 8 tied into the bight. Nice and simple.). I'm admitting that even SRENE is not an absolute, at least not in the real world. Moreover, every trad anchor set up is a little different, and what worked there might not work here. Bottom line: We can never standardize any protocol across the board and believe we've got the danger licked. The truth is born out in how the given anchor actually performs in the real world, not how well it adheres to the protocol. SRENE was devised to help make sure that the anchor performed well, but it never guarantees this. Though I would not recommend anyone violating the SRENE code, there are anchors out there that do not conform to the SRENE and yet these anchors are literally capable of holding a car. The anchor that prompeted this discussion presents a confounding situation--it did hold, and therefore did its job, so any criticism is strictly theoretical, not real. But any theory suggesting a single strand TR set up is one that sometime, somewhere, might bring the curtain down on someone. JL

I can't believe I am posting about this but, that looks like half an anchor to me. I like to see two anchor points some distance apart, to protect against a swing causing the webbing to rub across the edge :shock: If possible, in light of the above, another set of nuts to the climber's left of the ones in the pic would be nice. Certainly a second anchor point needs to be in there. Someone already talked about the SINGLE non-lockers and the single piece of webbing over the edge. I would never set a top rope anchor like this one. It sucks. Top rope anchors are the ONLY thing keeping the climber safe. let that webbing do a bit of rubbing and down it all comes.

But any theory suggesting a single strand TR set up is one that sometime, somewhere, might bring the curtain down on someone. Yours’ and other's contention that that anchor held a fall is purely theoretical as well. It probably held a fall is the best you could claim. It would be just as reasonable to claim that they could of done a number of runs on the top rope and cut the sling halfway through. In that case the anchor did not do it's job. (which is to stay in one piece) The preferable scenario would have to be that the guy who took the picture encouraged the people to fix their anchor before anyone got hurt from an inadequate top rop anchor. ps. I appreciate your insight on the overall anchor picture, and I agree with it completely

In a similar way, I like to say that Arno wrote the RWW as a set of tools, not a set of rules. Mindless parroting of what he wrote is NOT what the climbing author has in mind for the reader. Climbing goes so much better if the climber uses his head, and evaluates each situation accordingly. Thanks again for a great post.

I think the point of these anchor analysis threads should be to be as picky as possible. We're not setting up a real-world anchor here, but splitting hairs on an Internet website. In my opinion, the flaws in this anchor would not cause the anchor to fail. But that's not the point. The point as I see it is that this is an exercise in spotting those flaws. I've never had the misfortune to have the task of analyzing the cause of an accident, but from reading accident reports I've observed that many accidents occur as a chain of small mistakes that add up to disaster. So, the extreme nitpicking of these threads actually could be useful in training your eye to spot flaws that you might overlook. Personally, if I reached the top of the climb and found that anchor, I wouldn't really worry about it. If I was building it, I would probably try something different, who knows. In a top-roping situation where the anchor might be repeatedly weighted, I would worry about abrasion--as Curt pointed out. I know some of the players in this debate have more experience that I could hope to accumulate in my lifetime, but I hope you see the usefulness of the exercise. I personally find it helpful. Some of the critiques in the John Long were similarly nitpicky (and helpful). I recall that his books also clearly state that while the principles illustrated were indeed best practices, their application really depends on the situation.

IN this light a girth hitch is similar to a one loop prussic. Would you trust a one loop prussic for anything? There is another knot, I forget the name, that is esentially a 'one tailed prussic'. Even with three or 4 loops, you are cautioned to tie a stopper knot in the short end, because the end can pull out.

Well, the problem here appears to be that a few RC.com posters who apparently do not have enough climbing experience to actually determine what is safe vs. what is not safe are pretending that they do--and becoming holier-than-thou in their approach to climbing safety. Let's be absolutely clear about one thing and not confuse the cause with the result. Redundancy is not the goal in setting up a safe climbing anchor. Do not take your eye off the ball--safety itself is the ultimate goal and redundancy is only one tool that may be used to effect that end result. Redundancy can indeed sometimes cause an anchor to be safe enough to climb on--but equally so can other things. And, redundancy by itself does not make an anchor safe. Curt
