Fall on Rock — Rappel Error, Fatigue, Possible Haste, Washington, Beacon Rock State Park

FALL ON ROCK – RAPPEL ERROR, FATIGUE, POSSIBLE HASTE

Washington, Beacon Rocks State Park

On July 24, Nathan Turner (30) and his partner were in the second rappel of “Jill’s Thrill,” a common descent route for the area. The first rappel placed the two climbers onto a small ledge without incident. They lowered safely onto the ledge and setup their second rappel by threading the rope through the second set of chain anchors. Setup took longer than expected. Turner mentioned to his partner that it felt like he’d been “pulling rope a long time.” After this was said, they saw black markings on the rope signaling what they believed was the middle of their rope. Turner threw the side of the rope he’d been pulling up over the ledge and then setup his ATC to rappel. Last checks were made and he began his descent.

It started well enough. No failure occurred when the climber first took himself off his personal anchor. The failure occurred after a few seconds of lowering. Turner’s partner heard a loud “snap!” and then watched the rope rapidly unravel through the chains. He and two witnesses climbing an adjacent route then watched Turner free-fall, strike “Snag Ledge” below, and disappear from sight ultimately falling to the floor.

Analysis

It is believed that the rope wasn’t set with half the rope equally on each side of the anchor chains. What likely occurred is that when they initially missed the halfway markings, Turner kept pulling and centered the rope on the end warning marks. The rope they used was a 70 meter (9.4mm diameter) Petzl Fuze, which has markings both at the middle of the rope and at six meters (~20ft) from the ends. The markings in the middle are a solid black line. The ones on the ends are dashed black lines. The rope itself was blackened over a season of use but was in excellent condition. The rope with these markings is no longer in production. The surviving partner made contact with the manufacturer-Petzl-a few months after the accident and he was told they had decided-actually prior to this accident-that they had weren’t going to produce future ropes with any end markings on their ropes until the CE-European Committee for Standardization- established a unifying standard for all manufacturers to follow. The process for this standard is ongoing.

It is unsure exactly when he started his free fall. If he had been only rappelling on six meters of rope, the start of his fall would have been in-line with what they observed when he fell around 6–12 meters to his first contact point on Snag Ledge. This makes their account consistent enough to support the misbalanced rope hypothesis. The “snap” his partner heard at the start of the fall was likely the end of the rope whipping through the ATC. It’s not clear how the two mistook the markings aside from attributing it to end of day fatigue.

Nathan Turner was experienced having mountaineered for seven-plus years and had done technical rock climbing for two years. His partner was in his 4th year of technical rock climbing. Rappelling was not new to them.

For this scenario to be plausible, how could such a misbalanced and fast-pulling rope not slip free if it was so misbalanced? The proposed answer is that it wasn’t likely an issue of six meters of freestanding rope balancing 64 meters of freestanding rope. It was more likely six meters of rope balancing the distance from the anchor to Snag Ledge (~10m) where the thrown end of the rope had snagged (hence the name Snag Ledge). That unfortunate rope accumulation on the ledge left Turner in a situation where he wouldn’t have noticed the weight imbalance unless he or others around him looked at the ends and noticed something wrong.

Only one rope-end was confirmed to have had a Figure-8 knot. The other side could not be confirmed to have had a knot. It is unclear why. The most likely explanation is the knot did not get re-tied when the rope was re-threaded through the next set of chains. There was an irregularity in procedure that could have been the cause of the misstep. Turner’s partner recalls it was he, not Turner, who actually did the re-threading through the chains. After that there was an exchange like: “Hey, do you need to do anything with this?” “Nah, we’re good.” Turner’s partner did not re-tie a knot. (He wasn’t instructed to). If that rope was allowed to just freely lower and hadn’t ever gone back to Turner to tie the standard Figure 8 knot, it would explain how the knot didn’t get put back onto the rope. So, sometime when the two partners were shifting around to setup the rappel and fighting end-of-day fatigue, it’s likely that tying a back-up Figure 8 just didn’t happen and went unnoticed by both of them - as with the rope markings.

In prior documented cases of similar rappelling mistakes (of which two were found in prior publications of ANAM), common traits shared with this incident were:

Using ropes with extra markings.

Rappelling done at the end of the day.

The full rappelling path view was obstructed

Stopper knots weren’t used (or verifiably used).

The longer end of the rope stuck to something so the weight misbalance wasn’t noticed.
