The Prescription — April 2023

This month we have an unusual rappel accident. While this story has a happy ending, we cannot be absolutely certain of the accident’s cause. However, one theory seems to check all the boxes. For more details, read on.

Rappel Failure | Rope Became Unclipped from Anchor

Utah, Provo, Rock Canyon

On September 3, 2022, Kyra Harames (female, 24) was climbing with a group of friends at The Kitchen in Rock Canyon. After setting up a top-rope, she fell to the ground while rappelling from the two-bolt anchor.

Harames reported to ANAC, “I remember everything leading up to my actual fall, and the rest of the details my friends filled in. At about 8 a.m., I successfully led Panic City (5.11a). After I set up that route with a top-rope, a couple of my friends started climbing it. I then hiked to the top to set up another route called Left Corner (5.9). I clipped in my daisy chain as a safety with a locking carabiner. I set up the top-rope using two wiregate quickdraws on the same bolt. I put both strands of rope through my belay device to rappel and used a locking carabiner. I checked the rappel and put my weight on the belay device/rope before taking off my safety. Everything seemed good, so I proceeded to rappel. The last thing I remember is lowering myself a couple of feet, and that is when I fell.

“The rope came out of the quickdraws, and I fell about 35 feet. My friends said when I hit the ground, they could hear the air leave my lungs. I briefly landed on my feet at an angle, and then landed on my back. One of my friends called 911. Shortly after that, I lost consciousness. A nearby climber came over and couldn't find a pulse. My close friend Alivia did CPR and less than a minute later, I regained consciousness. The ambulance came really quick. A friend ran down to make sure the gate was open for the ambulance and it was able to drive up all the way to me.

“I have a very vague memory of being in the ambulance. I didn't know what had happened, but I had a dream that I was climbing. My first solid post-fall memory was when I woke up in the trauma room. I had no idea what had happened. The nurses filled me in. I got stitches in my foot and elbow, as well as staples in my head. I had a compression fracture on my T11 [vertebra], a mild concussion, bruised ribs, and a fractured talus bone in my ankle. I stayed for a day and a half for monitoring and pain control. The reason I went into cardiac arrest after my fall is believed to be caused by a phenomenon called commotio cordis. This is when an impact to the chest occurs during a short vulnerable window in the cardiac electrical cycle. 

“A week later, I received surgery to repair my talus and they put two screws in my ankle. I took a leave of absence from medical school to recover from my concussion and other injuries. 

“Currently, I have made a full recovery physically and mentally. I have caught up on medical school and have started to climb again. So far, I have only top-roped in indoor gyms, but hope to go back to climbing outside. I am thankful for my friends and family for helping me through my recovery and everything I learned from my experience. It truly was a miracle.” 

ANALYSIS

Two strands of rope were running through Harames’ belay device, which was attached to her harness with a locking carabiner. The entire rope was on the ground after the fall occurred. The quickdraws were still attached to the anchor. 

Harames writes, “Looking back on it, my friends and I have tried to figure out why the rope came out of the quickdraws. It is possible that they were facing the same way, which may have contributed to the rope unclipping itself as I rappelled. I believe this could've been prevented using locking carabiners.” 

In principle, Harames did the right thing by using two draws at a bolt belay. However, she made a fundamental error in using only one of the available bolts. Sport belay stations almost always have a minimum of two bolts. Always incorporate both in any anchor system.

Why did Harames not do so? One clue might lie in the positioning of the belay bolts and the style of hanger used. The bolts here are on either side of a small arete, positioned in such a way as to allow top-roping on both Left Corner and Mark’s Corner (5.7) to the right. Harames later wrote, “I don't remember why I clipped the rope to only one bolt, I might not have seen the other bolt around the corner a little bit.”

Setting up a top-rope with the rope through at least one locking carabiner is always a good idea. (Many climbers always carry an “anchor draw” constructed with locking carabiners for exactly this purpose.) If you don’t have a locker, it’s important to oppose the gates on the carabiners through which the rope is running. 

It is extremely unlikely that simply leaning back on two anchor quickdraws would cause them to come unclipped. If this were so, any link in the belay chain using a rope clipped to a carabiner—a quickdraw on a run-out sport route for instance—would be suspect. Nonetheless, the best practice is to oppose the carabiners, because there are scenarios where for the rope could unclip—see the photos for an example.

Another factor that comes into play is the height of the anchor. When one stands atop Left Corner, the anchor bolts are at waist level. This height might have contributed to this very unlikely accident. As one pulls up the slack on an ATC-style rappel device, it is possible that the tightening loop of rope can wrap around the carabiner gates—see the video. This is made more possible if the quickdraws lie parallel to the rock surface and incorporate both stiff sling material and pronounced bent gates on the lower, rope-bearing carabiner (typical in most modern high-performance draws).

Patrick Begley wrote on mountainproject.com that if two draws on bolted anchors were oriented in parallel rather than gates opposite, “complete detachment of the rope is certainly possible, especially if the climber was firmly gripping the draws in preparation to weight the rappel.” Begley is an aerospace engineer, an AMGA Single Pitch Instructor, and Apprentice Rock Guide.

While unlikely, this scenario is possible when stiff, captive lower carabiner quickdraws are both clipped to a single point. Begley wrote, “It was quite difficult to replicate.” Photo by Patrick Begley.

TAKEAWAYS

  1. Always incorporate two or more bolts into any anchor system.

  2. Weight test the rappel anchor. Put your weight on the belay/rappel device and rope before you unclip your PAS or other backup. Though Harames did this, it’s possible she did it while holding the draws in the manner depicted in Begley’s photos.

  3. Consider using locking carabiners and a cordelette or long sling. AlpineSavvy climbing guide John Godino’s website has some good resources on cordelettes and clipping the horizontal-style ring hanger as found on Left Corner.

  4. Oppose the carabiners, especially if you’re not using lockers.
