Jonas Wexler was on the second pitch of a six-pitch granite route in a remote drainage of the North Cascades on the morning of July 9, 2025, when a hold broke and he fell roughly seven meters before his last piece of protection caught him. The piece held. His belayer, his longtime partner Ana Ferreira, caught the fall cleanly. He swung into the wall on the way down and struck his left side against a low-angle slab.

He had three broken ribs, a bruised lung that began to show as shortness of breath within the hour, a deep contusion on his left hip, and a sprained wrist. He did not have a head injury. He was conscious and able to communicate clearly.

He and Ferreira spent the next 19 hours getting him to a trailhead from which Ferreira could drive to a hospital.

Wexler, 41, a high school physics teacher from Bellingham, has written a long, detailed account of the self-rescue for a climbing magazine. The account, which is technical and unsentimental, has been widely shared in climbing safety circles for its specificity about what worked and what did not.

The route was in a drainage about 14 kilometers from the nearest trailhead, with no cell signal at the base of the route and intermittent signal only near the trailhead itself. The pair was carrying a satellite communicator, which Ferreira activated within ten minutes of confirming that Wexler was breathing and able to move his legs. The communicator sent a non-emergency message to a friend in Bellingham who served as their backup contact, indicating that they had had an accident, that Wexler was injured but conscious, and that they were going to attempt to walk out rather than call for a helicopter.

After a lead fall on a remote granite route in the North Cascades, Jonas Wexler had three broken ribs, a bruised lung, and no cell signal. He walked himself out over 19 hours.

The decision not to call for a helicopter is the one Wexler has been asked about most. He has explained it carefully. He was breathing, though shortly. He could walk, though slowly. The drainage was tight and steep, with no obvious helicopter landing zone within a kilometer of his position. A helicopter rescue would have required either a longline operation or a long carry by ground team. Both would have taken many hours to arrange, and both would have put rescuers at risk in terrain where, he believed, he could move himself.

He was, he has acknowledged, making a judgment call about his own condition that not every injured climber should make. He has been clear that the call was based on his ability to breathe, to walk, and to think clearly, and that if any of those had degraded he would have stopped and waited for a longline.

Ferreira rappelled him off the route on a single line, with him on a third-hand backup and her below him as a fireman's belay. The rappel took roughly two hours for what would normally have been a 20-minute descent. He could not lean back against the harness without sharp pain on his left side. He used his right arm and right leg to manage the rope and his body position. He vomited once during the first rappel from the pain, which he has said was the only point during the day when he considered changing the plan.

At the base of the route, they triaged. Ferreira built a chest wrap from a foam pad and athletic tape from her first aid kit, which stabilized his ribs enough that he could walk without each step causing a stab of pain. She carried both packs. He carried nothing.

The walk out took 17 hours. The trail was rough, with several stream crossings and one short fourth-class step that he downclimbed on his right side, with Ferreira spotting from below. They stopped every twenty minutes for him to rest and to monitor his breathing. He sipped water continuously and ate small amounts of food on a schedule, even when he was not hungry, to maintain his blood sugar.

Ferreira sent a satellite update every two hours to their backup contact, who relayed their progress to a small group of friends who were prepared to call for a helicopter if the messages stopped. The messages did not stop.

They reached the trailhead at 4:30 the following morning. Ferreira drove him to a hospital in Sedro-Woolley. He was admitted with the broken ribs, the bruised lung, and early signs of dehydration. He was discharged after three days.

He has been clear, in his written account, that the self-rescue worked because of factors that were in place long before the fall. He and Ferreira had practiced rappelling an injured climber. They carried a satellite communicator and a real first aid kit. Their backup contact was a person they trusted to make the call if they went silent. Their rope and rack were adequate for the route, with redundancy. They had eaten and hydrated well before the climb.

None of these, he has written, are exotic preparations. They are the preparations that climbing instructors describe in every basic course and that most climbers, including himself before the fall, treat as optional once they have a few seasons of experience.

He returned to climbing five months after the fall, on short routes near home, and to alpine routes the following summer. He has continued to climb with Ferreira. He has added one practice to his routine: before every multi-pitch climb, he and his partner now run through what they would do if one of them were injured at each pitch. The conversation takes about ten minutes. He has said that it has changed, in small ways, how he climbs.

He still teaches physics. He uses the fall, occasionally, as an example in his unit on rotational motion. The students do not always believe the story. He shows them the chest x-ray from the hospital, which he keeps in his desk drawer. They believe it then.
