Disclaimer: No one was injured during the recreation of this anchor. I saw this exact setup at the top of Kens Crack this past Saturday. That's it. That's everything.. (except the two locking biners on the end of the red cord) Entire anchor description: One 5mm cord girth hitched *high* up on a tree. One 7mm cord girth hitched to the blue cord. Two locking biners on the end of the 7mm cord with the toprope running through. No one was climbing on the rig while I walked by and I was thinking of dismantling the whole thing and throwing the rope down... I should have. Earlier in the day I saw a half dozen kids taking laps on the route. I talked to one lady who seemed to be with that group and mentioned that her anchor was unsafe and inadequate. She gave me a blank stare and replied with "uh huh". I talked to some other climbers in the area and they informed me that an amga guide had previously gave them the same spiel that I did to no avail. I then proceeded to walk away to avoid having to be involved in any rescue. To the fellow rc'ers... What would you have done?

I cut up the cord, bring it to the owner, offer my personal cord and show them how to set up properly, letting them keep it. I get tons of shit free/cheap so I'm not against the karma points of sharing the love. or 2. If the person is a royal doucher, I cut up the cord, throw it down and say "You're an idiot, go home" Option 3 would only be if I was a dude, I'd just go to the edge and piss down on their shitty anchor, their rope and the idiot who will climb on such a time bomb.

Why would you cut the cord?

kobaz, Was the guide Joe Vitti? http://gunks.com/...y_Night_Li#Post67688 Perhaps that was the anchor he saw that inspired today's posting on Gunks.com The red and blue knots are actually joined with a square knot. Still unacceptable, and a dangerous knot to use at all in any climbing application. http://www.animatedknots.com/...ww.animatedknots.com Although the anchor you saw probably had continuous loops of chord not likely to capsize, joining them that way is also dangerous. ( As you noticed)

I would find the leader and point out the dangers. Imagine how you would feel if you didn't and there was a fatality. In many situations it is difficult pointing out dangers when the climbers seem to be experienced. You know you are going to get an arrogant f.o. response. I once pointed out some belaying errors to a such a fellow. Minutes later he dropped his female climbing partner onto his own head.

( As you noticed) I think that's actually a strop bend, not a square knot. They have the same shape; it's basically a variation of a girth hitch. I don't believe that there is a significant risk of capsizing since all of the strands would be (nearly) loaded equally (based on the assumption that the red cord is tied in a loop). I'd say the cord mechanics are okay but the sizing is a little small given that there is no redundancy.

Unrelated to this anchor...there was already an accident at the Gunks this season. A belaying accident where the belayer could not hang on to her second. He fell 60 feet and sustained broken ribs, scalp laceration. He is expected to make a full recovery. Belayer sustained significant burns on hands. We have a lot of gym climbers transitioning to the great outdoors. I suspect many of them are simply too inexperienced to climb safely. It's often difficult to figure out when to intervene. I find myself leaving the area more often then offering any suggestions. That said, I have taken over belays, assisted with rescues, stuck climbers etc.

I've read research and drop tests where a cord/sling of sufficiently smaller size is girth hitched to a larger piece, it will cut when highly loaded. Square knot, strop, etc... one sling is essentially girth hitched to the other. I would say that given there are a million and one other, better ways to rig this setup I would not be okay with the cord mechanics. And yeah the sizes are pretty bad to be the sole anchor.

From what I understand she was belaying her second without a re-direct (she was belaying from the top)

which is fine if you know what yr doing i suspect she wasnt practiced in catching those types of falls where the ATC flips, or you need to set it up differently ...

Here's a newbie question, from someone starting to transition to outdoor climbing: what exactly was wrong with that setup? 1. The high girth hitch I assume was problematic because it creates greater torque on the tree 2. Only having a single rope is dumb because there is no backup if the only anchor fails. 3. Is there a problem extending the rope that way? More likely to fail at the knot? 4. Is there a problem attaching ropes of different diameters to each other?

Is there a problem extending the rope that way? More likely to fail at the knot? 4. Is there a problem attaching ropes of different diameters to each other? 1 Yes. Stronger at the base instead of up high. Of course, with a BIG tree it doesn't matter so much. There are ways to arrange a girth hitch to lessen strain on the cord. And there are better ways than a girth hitch. 2 Yes 3 The Strop Hitch shown is not necessarily bad. But, the 5mm cord was too thin for my likes. 4 Not always. A 10mm and 8mm cord are different sizes, right? But, in this case, the 5mm cord was too thin. Primarily: no back up & cord was too thin. IIRC, the tree at the top of Ken's Crack is fairly large. Still, larger cord and a master point over a padded edge would be a goodthing®.

when you climb enough multi ... youll eventually belay off a large single tree with a single sling, often girth hitched

The point is, there's a big difference between making a judgement call on a multipitch and saying that "this 7mm cordalette anchor on a 10 inch diameter tree on this 5.3 scramble pitch is sufficient" versus slinging a tree with tiny cord as your sole anchor for kids to toprope on all day. A high girth hitch does put more torque on the tree, but in this case the tree was big enough to withstand being pulled from higher. The problem in this case however, was given the height of the girth hitch and size of the cord, there's a real risk of it slipping down the tree as it gets load cycled, possibly abrading and weakening this single point anchor to failure.

the problem is the cord thickness ... with a thick cord or rope, im not worried about the girth hitch one bit as to the "placement" on the tree ... a basket hitch, etc ... could also "slip" down ... but realistically a nice round tree isnt going to cut a thicker sling/cord/rope ... as to TR anchors ... lead anchors need to withstand MUCH higher forces .. so realistically if you arent going to put whats basically bodyweigh + the pulley effect ... you shouldnt be leading off it if you have any choice
