On July 15, 2005 at 4:30 pm I was injured when I dislodged a large rock while climbing a short class 3-4 chimney on Tuolumne Peak in Yosemite National Park. I was climbing alone collecting data for a research project exploring rockfall. I had not informed anyone of my itinerary, carried no cell phone, and was not wearing a helmet.
The research project had taken me to nearly the same spot the previous Monday to determine rates of cliff erosion by rockfall. On this Friday I had completed 2 sites and was heading for a third at a large cirque amphitheatre on the southeast flank of Tuolumne Peak near Tuolumne Meadows. Approaching the site I was stemming an inside corner when I grabbed a hold above my head and dislodged a large rock. The rock was about twice the size of my chest and it came free from the wall easily, causing me to fall about 15 feet in an upright position. While falling, the rock was at the level of my chest and I fought to move it away from my body. During the fall the rock crushed my left ring finger, nearly severing it, and struck my right forearm, opening an 8 inch gash and destroying much of my forearm muscle. I landed on my feet and badly sprained one ankle (at the time I thought it was broken).
I assessed my situation noticing significant bleeding from my right forearm. Both bones in my arm were visible but neither were broken. My right hand was rendered useless due to the muscle injury, clasped closed without the opposing muscles required to keep it open. I quickly dropped my backpack and took off my shirt to wrap my arm at which point I was alerted to my left finger injury. The finger was almost totally severed, dangling by a small thread of tendon, but was not spurting blood. At the time, I considered pulling it off to ease my descent but did not. The combined injuries left me without dexterity making it difficult to wrap my shirt tightly around my open arm wound.
Looking up I could see Tenaya Lake four miles in the distance where my car was parked and where I would find help. I cursed myself for not having a cell phone but was thankful I was able to walk. Before descending I opted to reshoulder my backpack which had in it a treated nylon jacket, long underwear top, water, food, headlamp, maps and aerial photos, a compass, and an emergency space blanket, none of which I could easily retrieve due to my hand injuries. I placed my left hand atop my right forearm so the shirt would soak up the blood from both injuries, and did my best to hold both arms above my heart.
I began descending over steep slabs, ledges and boulders within 1 or 2 minutes of my fall. I had studied maps of the area well and knew there was a trail some 2,000 vertical feet below the accident site, but in attempting to follow the most direct route I was stopped by terrain too steep to descend in my condition. Backtracking and moving to a lower-angle route, I reached the trail in about 1 hour, during which time I suffered the first of two very painful tripping incidents. I remembered from the maps that once I reached the trail I should head in a counter-intuitive direction, away from Tenaya lake, before the trail would swing around to the proper heading. Unfortunately, I arrived at the trail in a different place than I thought I would, and after walking for about a half an hour I realized I was heading the wrong way. I turned around and hiked out. During my 2 hours hiking on the trail I was badly attacked by mosquitoes since I was covered in blood, wearing no shirt, and couldn’t fend them off with my hands. This stands out in my mind as being the worst part of my day. I also fell another time while crossing a slickrock stream which, aside from being painful, soaked my cotton pants. I encountered no other people on the trail.
I reached the highway at 7:30pm, 3 hours after the accident, and immediately flagged down a car which slowed, looked me over, and drove on. Another car came shortly, and I was driven to the Tuolumne Meadows ranger station. There were no rangers inside so I was helped out of the car and sat on the steps while the driver went to go find one. Before leaving, my helper took off my backpack, first having to peel my left hand from atop my right forearm which had scabbed to the shirt wrapping my wound.
When the Yosemite rangers arrived they decided to take me down to the Mammoth hospital. However, leaving the ranger station in the ambulance we headed west instead of east on Hwy 120 until after about 5 minutes I spoke up and we reversed our course. In Mammoth I was treated very well, undergoing 4 hours of surgery to first clean out the rocks and mosquitoes from my right arm then pin together the complex fracture on my left finger. I was in the hospital there for 2 more days before being flown to San Francisco for micro-surgery to repair my damaged nerves and muscles.
Now, one month after the accident, both my arms are splinted and immobile making every function difficult and requiring near constant care. This accident report is, in fact, typed letter by letter with a pencil strapped to my left splint. At this point I cannot open my fingers or thumb on my right hand, but my left finger is successfully reattached.
As for lessons learned, I think a couple are fairly obvious: let people know where you are going, carry a cell phone if you hike alone, be weary of loose rock, and wear a helmet on steep terrain. I feel very lucky that the rock did not strike my legs or head or I may have not been able to walk out of there and, because of the circumstances, it would have been days until I was reported missing.
