First thought was to argue the numbers since I think they support that the basic belay was as good as it could be - except for maybe pre-tensioning with full body weight or setting an intermediate belay.

Second thought was that, yeah, a leader has responsibility for setting up the situation regardless of whether or not the stretch-numbers would stack up on the belayers side in the end.

it would have helped if he had extended the anchor to the edge, rather than ten feet away from where he was. Izmuch easier to pre-tension skinny ropes auto-blocked with an ATC-Guide when it's sitting right there in front of you, but nearly impossible when it's not.

I understand your point but consider... bouldering often doesn't merely hold the threat of falling, but the expectation.

In my case I have broken both ankles and the last break didn't heal all that well. A high ball bouldering fall is simply not in the program.

Its different, s'all.

iz tru.

thing is, most inexperienced climbers not familiar with the elastic properties of half-ropes would never expect to hit the ground when they decide to give up and weight the rope, nor when they simply pop-off unexpectedly.

I think were the situation to present itself again, a leader would be well advised to lead on a single 10.2, while trailing a second single-rated rope as well, the increased costs in weight be damned.

The second can clip the trailed rope through the pro to protect the third, at least often enough to prevent potential pendulum falls. I'd still probably put the least experienced climber in the second position, and the other qualified leader or the more experienced second in the third position, such that they can clean all the gear without unexpected problems.

Bullshit. Although not always possible or desirable, in most cases the leader should simply put the second on sufficient tension at the beginning of the pitch so that if he falls he won't get hurt. I'm amazed by how many belayers I find who have never even considered this.

Perhaps I was unclear. I was referring to the specialized case where pulling sufficient tension on the line was not possible (short of a haul system or something like that). I believe that was the original scenario (the leader had tensioned the line?).

I kind of take it as a given that the belayer above is going to try to take as much slack as possible if there's a difficult/risky start. Perhaps I assume too much.

The important thing for people to take away from this is that tension on the belayer's end does not always equal a short fall on the follower's end of things -- particularly with great lengths of rope and rope drag in play. Most of the time this is not a big deal: either the follower is on easy ground, or the fall is clean. Regardless, the team needs to be able to recognize the risk and deal with it as they see fit.

if the leader would have had the foresight to know that a low crux + stretcy rope were going to cause a problem, one solution would have been to plan on bringing up both seconds independently. Doing so would have allowed a re-direct from a high-point anchor with a direct belay from the harness. This would also have allowed the top belayer to add his/her body-weight to the tension equation, simply by jumping up and removing slack from the system, using their own body-weight to pull stretch from the rope.


In this particular case, with the stretchy half-ropes, I doubt that even this technique would have been sufficient to prevent a decking.

Which leaves two reasonable options from where I'm sitting.

1: split the pitch up. it sounds like there was a good ledge less than half-way up the pitch.

2: use single-rated ropes and tension the seconds aggressively while they are near potential obstructions on the route.


Perhaps a less reasonable option would be to stay in the gym, don't climb outside where unforeseen dangers might exist. Even though, it is the option many would rather be exercised.

The crux on Double Crack is not 15 to 20 feet up. Unfortunately, the woman seconding somehow managed to fall there anyway.

"In most cases" does not mean "the specialized case." In fact, it means the opposite.

What I wrote could clearly be misconstrued, so mea culpa there.

In fact, I meant "in most cases within the subset of specialized cases which are the topic of discussion of this thread". But that sounds kind of cumbersome. The whole gist of the original sentence was supposed to be: "In the majority of scenarios where the second will risk a 10-foot fall due to rope stretch at the beginning of a pitch, most parties will choose to accept that risk and do little to mitigate it. Compared to other risks taken by the party during the course of a normal climb, that risk is relatively minor."

I think the real problem is not the people taking that risk, but those who fail to realize they are taking that risk.

Hopefully I've cleared up any confusion about my initial, incoherent ramblings.

By the time I'd posted that, I was in my hotel room and had availed myself of the opportunity to read the mess. <<--- I was thinking of a post I'd made later in the thread. My bad.

yes, but the fact remains that he was auto-blocking through the anchor, rather than using it for a re-direct, which was ultimately kind of my point. One method will offer more opportunity to add tension to the TR system than the other method will allow. I know YOU know this, but...

We could make the point another way-- the first section of any lead, and often the first section of any second, is frequently a free solo.

stymingersfink, Your idea about belaying off the harness and redirecting through the anchor was something I had not considered. Still, at most, that would take out just a couple fee of slack which, on the next attempted stroke, could just get sucked back out. On the other hand, do what you said and also put an anchored prusik on the line to the climber. Use body weight to bring in rope, slide prusik, prep for next stroke, repeat. I did this once but was lifting with my legs instead of re-directed through the anchor. Next time - if there is one - I'll try it your way.

Note however that this sort of cycling tends to act on pro where the rope takes a change in direction. So, cams might walk or something iffy could let go. Pro at changes in rope direction ought to be bomber regardless of this rope-stretch issue.

Aye we're in agreement klk. I just felt compelled to point out that a lot of bouldering holds the clear prospect of falling, where as a lot of trad does not.

Just sort of a mindset thing, tis all.

You're a trad boulderer btw....

Apologies to Dick Williams,

Trapps Guide Second Ed., 2001:

382 Double Crack 5.8 G ***
This is a great, classic climb, steep and exciting, best to do in one pitch. Double ropes are needed for rappel.
START: At a crack with a chockstone 10 feet up, 50 feet right of Uphill All The Way and forty feet downhill from Broken Hammer's huge dirty corner.
PITCH 1: Climb the crack (crux), then left past an alcove to a ledge (optional belay). (70 ft., 5.8 G) Move up left and climb the crack and off-width to the overhang, step right and up the steep face (5.7 PG) to the belay/rap-station. (150 ft.)
FA 1955: Jim McCarthy and Hans Kraus
FFA 1958: Jim Geiser and Jim McCarthy

Of course you might not trust the guidebook, so here are several comments from rc.com:
"First pitch - hardest moves seemed to be at the start of the climb"
"as mentioned in desc. hardest near the start"
"Crux is the first part of the climb, maybe the first 30 feet. After that it backs way off."

IMO, the "crux" is above the chockstone and below the first small ledge at 25 feet.

Here is an excerpt from an e-mail sent to me by the injured climber:
"...my indoor climbing reflex kicked in and I sat back to study the problem-just did not expect the stretch to take me all the way down!"
(But I don't discount the possibility she said that just to ease my own sense of culpability).

Really, I just shouldn't bother, but I can't shake the feeling that there might be a handful of people who read these forums who actually want to avoid getting hurt or hurting others. If you're one of those folks: run away. Others, apologies for the interruption, continue theorizing at will.

Your idea about belaying off the harness and redirecting through the anchor was something I had not considered. Still, at most, that would take out just a couple fee of slack which, on the next attempted stroke, could just get sucked back out.

No, you can take out a lot more stretch than a couple of feet. Again, I'm amazed that people can climb for more than a couple of days and not know this technique. If you don't know how to suck slack out of a top rope, then you are frequently putting the top roped climber (including a second) at unnecessary risk at the start of the climb and when they leave a ledge.

As Sty said, you rig the anchor high, belay off your harness, and redirect the belay through the anchor. You have now essentially mimicked a sling-shot toprope setup. Put as much tension in the rope as you can by using brute force. Then, with your brake hand locking the rope off, grab the rope as high as you can with your guide hand. Then, do the following three things simultaneously: (1) pull down with your guide hand, (2) jump, (3) pull slack out of the rope by pulling up with your brake and quickly returning it to the braking position. You can perform this maneuver repeatedly to increase the tension in the rope, up until you can no longer stand firmly on the ground. Still not enough tension? Have the second climb a few feet up, and repeat the maneuver a couple more times.

With 150 feet of rope out, you can pull out a lot more than a couple of feet of slack like this. By pulling down continuously with your guide hand, friction through the anchor prevents the rope from sliding back on each jump, the anchor essentially acting as a ratchet.

Last summer my partners and I spent a good deal of time top-roping several roughly 130-foot long routes, using a sling-shot top rope (ie, the belayer was on the ground). Even with 260 feet of rope out, we had no problem sucking sufficient slack out of the rope so that we could leave the deck, and an intermediate ledge, safely.

stymingersfink separately helped me see that the weighted redirect without prusik should work to get out significant tension. Basically, it is not so different from a top-rope set up with the belay from below for which I have done this very thing. Of course, at the anchor the belayer will be a little more constrained.

Thanks!

Edit: And I see Jay made it quite clear above.

Given the audience for this site, we should probably add the caveats: This works best for climbs with ultra-bomber anchors, that are mostly vertical or slabby, and mostly straight up-and-down. If the climb starts with a traverse or a steep overhang, the tension is going to work like a slingshot with potentially interesting results.

There are times when I will actually lower myself down my side of the rope such that I can see my seconding climber. In such situations I must be able to get my weight on the rock to utilize the technique outlined before in order to re-ascend my side of the rope when it is no longer necessary for me to be within visual range.

^^this is usually done on easier climbs, when I've got a rank beginner with me, or perhaps a situation arises that I need to see to be able to come up with a solution, as none seems to be forthcoming from below.. certainly ain't gonna happen on some overhanging dog-fest.Smile

and my anchors, by defintion, are bomber. Period.
