an unexplained accident

I was recently involved in a lowering accident - I was not the injured party nor was I the person doing the lowering but it was in my climbing group for the day.  I really don't want to go into all the details for  analysis here (I hope that is understood)  We talked it over with each other, as well as with other experienced guide folks and went over everything that transpired.  Essentially we cannot account for how and why the person being lowered fell.  Nothing points to a sound explanation of belayer error, device failure, anchor failure, or anything else conclusive.  The practices used for the situation we were in were deemed "sound" - nothing really strange or out of the ordinary.  But something obviously went wrong we cannot account for.

My question is this - has anyone ever been involved in a climbing accident where its essentially like WTF?  We did nothing wrong but obviously something went wrong and we can't explain it.  How do you mentally reconcile that?  We do our best to be safe and follow best practice.  I recognize climbing is dangerous and things happen - there are always circumstances and things that happen out of our control.  But that is a bit of difficult thing to swallow...anything can go wrong at any time regardless of what you do...yes I know thats how life is - its accepted risk - but an event that appears to be an "anomaly" or "freak accident" in a normal, frequent climbing procedure is a bit unnerving.  Has anyone ever experienced something like this and what did you do?  Just chalk it up to an accident and move on?  Recently I listened to a podcast where a guy was climbing in el dorado canyon and all of his bomber cams inexplicably ripped and he discussed it at length.  This isn't what my group went through but similar in some ways.

it wont let me post below so adding here:

EDIT  ok - I will try and make this as simple as possible - a climber was on an anchor at the top of a climb on a large ledge.  was going to rappel but realized the rappel device was left on the ground by accident.  on an adjacent climb off the same shared anchor another pair had a TR set up. a decision was made to use this rope to lower the climber.  the climber tied a fig 8 on a bight to a locker to belay loop on the non gear side of the rope.  initially they were going to tie into the end and pull up all the rope but it was an 80 meter rope and they decided to go with the bight.  it was confirmed there was enough rope on the ground to get them down.  they clipped in and weighted the anchor while on PAS.  taken tight from the ground they were lowered about 75 ft with no issue.  about 25 ft up from the ground they fell and the rope was running.  I was above on rappel watching.  Prior the fall it seems the climber had noticed rope of some sort in a crack - it may have been slack - it may have been tail off the bite - that is unknown.  The belayer says as the climber fell the rope was not running fast through the device.  The rope was still in the device when they hit.  No gear had pulled on the gear side.   They were still completely tied in when they decked.  No gear failed up top.  Everything was bomber and solid.

All we can speculate is, as someone said above - somehow the rope got around or in a feature of some kind that "popped" and caused slack to release coupled with the person stopping at a small ledge on the way down as others have said - maybe it was 20 or 25 ft?  I am not sure. This is what I know based on what I saw and what was discussed after.

Miraculously this person only suffered an injured foot.  As I said, it looked very bad.

Without details, you’re basically inviting a shit-show of speculation to occur.

In my experience, if you can’t figure out what exactly went wrong, it was a user error, and the user that erred is not remembering the events correctly for a variety of reasons.

I know - i am contemplating deleting this - I am hoping it can stay ok - I am just kind of having difficulty with it.  I suspect it can be user error or any number of things - I just don't know what they are nor does anyone from the group.

Essentially a climber was lowered off the top of a 100 ft pitch.  75 ft down all was well.  25 ft up from the ground slack peeled out...from the climber side of the device - not through the device - like a 30 ft length of slack "appeared" and the climber fell.  It looked very bad but fortunately injuries were not overly serious.  I was above the climb on another line on rappel at the time.  The climber was taken tight at the anchor on top rope, lowered 75 ft with no issue and then just fell.

It would be helpful to provide as much information as possible amongst yourselves, and if it helps, here.  'Shit happens' situations are more rare than climber error.  It may take awhile to figure out, but is worth all the reflection time possible so that the accident does not repeat itself.  

Again, sorry that you were involved with this.  I hope it get resolved!

i removed the post mortum comment - the climber is ok - certainly not dead...although it looked that bad from my vantage point at first TBH

This is nothing like “cams exploding inexplicably”. You can’t ask for an advice without explaining what happened. Lowering accidents in most of the cases, I’m yet to hear otherwise, are user error.

Everything happens for a reason.  I don't mean in a predetermination sense.

What belay device was used? Sounds like belayer error to me.  Thirty feet of slack doesn't just "appear".

It is possible that this could be an anchor issue, or a run of rope issue, rather than a belayer/device issue.

it was a gri gri - I understand everyone's point - I have a seperate synopsis I compiled - perhaps I should share it

If a climber partially unweighs the rope near the bottom of lowering (e.g. standing on a small ledge) the rope stretch when they weigh again can be surprisingly far. I once saw someone hit pretty hard from about 10 feet for this reason. We understood why immediately after it happened but were surprised by the length of the fall. It's a common mistake with beginners when lowering.

Rope stretch doesn't explain 30ft of distance in a 100ft of height, but the sudden increase in force could have also caused the rope to pop off an edge at the same time.

None of this accounts for 30ft of rope, but maybe it wasn't really 30ft?

One possibility is: The rope may have been caught behind a slightly protruding piece of rock, and when the rope popped over it, the rappelling system could experience a nearly instantaneous availability of slack on the climber's side.  One must be aware of the rope's position on the rock, when being lowered, to prevent this from causing an accident.   I am very sorry for your friend.  I hope they recover soon. 

If somebody is dead something definitely went wrong.   Whether the "reasonable person" could have foreseen or prevented an accident is the question. There are so called "acts of god" and human error.  

Someone getting dropped lowering to me immediately points to human error.  Whether that was gross negligence or a rare situation that the reasonable person could not have foreseen I don't know.  I wish you the best with your healing and hope you get answers to your questions.  When I get lowered the person literally has my life in their hands.  If I end up injured they are the first person I'm gonna look to for an explanation.

Sounds like the the rope was actually hung up on something when the climber started being lowered, and then got loose, or like the other poster suggested, part of the anchor failed. Was it a gear anchor,  bolts, slung trees? Did you all inspect the anchor afterwards? 

Was the climber cleaning the route, or just lowering straight to the ground?  Was the route overhanging, vertical, or less than vertical?

it was a gri gri 

This type of accident is fairly common with Gri Gri devices.  I'd guess that many of these incidents are never reported or published because many times, people are able to walk away with minor injuries.

Typically, here's what happens:

The belayer is using proper gri gri technique by opening the locking mechanism with the left hand while controlling the lower with their right hand on the brake strand.  For whatever reason (fatigue, friction burn, distraction, etc.), the belayer loses control of the brake strand.  The left hand instinctively pulls down hard on the brake lever, which holds the camming mechanism open and sends the climber into free fall.

lead climb and the top anchor got unclipped somehow??  Sorry now we're just speculating.

How was the climber attached to the rope? Were they attached to the rope when they decked? Based on the limited information provided it sounds as if the knot untied/wasnt finished and slipped through itself causing the climber to fall and the rope to recoil from the load suddenly releasing. This would explain the slack above the belay device.  There are certainly freak never before seen accidents but this doesn't sound like one of them. If you cant figure out how this happened yourself use that as a learning moment to identify a gap in your knowledge of what could go wrong and learn from it.

I suspect that this analysis may be going down the wrong rabbit hole with the focus on the GriGri. The OP already stated that the rope did not slip through the device. 30’ of rope shooting through the device is something that you’d notice (rope burn). So the excess slack apparently came came some other factor.

As stated above by several people, this could happen in various ways. Part of the anchor failing, a directional coming unclipped, the rope bring caught on a protruding piece of rock then coming off, etc.

Need more specifics of the route and anchor configuration before we can speculate further.

Forces on the system are minimal in lowering compared to lead falls.  Therefore, 100% user error.  Go back and have an honest conversation to figure out what actually happened or avoid climbing with the involved altogether, which would be my choice.   Best of luck. 

There's always an explanation. This actually sounds like something that happened to me once, I slipped unexpectedly and fell 25 feet into rocks (I was fine!) while following a pitch and with rope being taken in as normal. No extra slack. Belayer never noticed a thing. What happened was the pitch went went through a large angle and of course the rope followed this zigzag. When I slipped a piece pulled (the piece at the sharp angle) and a whole lot of slack was created. No one did anything wrong. The same effect can occur, while lowering, from the rope running around something like a flake or an arete that's not really in line with the fall line; at some point the rope may free itself and cause the person being lowered to suddenly fall some distance.

This effect is amplified by the dynamic nature of a climbing rope. Under bodyweight (lowering) the rope does not stretch much; but subjected to a larger force (a fall) the rope is designed to stretch, maybe quite a lot, in order to soften the impact on the person.

30 ft is a lot of rope to be stuck in a crack or let slack by a anchor slip... I am saying the same as others, user error and unwillingness to accept that they screwed up.
