Roped-Together Climbers Die in Fall On Mount McKinley in Denali National Park and Preserve

Two acclaimed climbers who were roped together while climbing on Mount McKinley in Denali National Park and Preserve have fallen several thousand feet to their deaths.

While two medics and an emergency room were quick to reach the two, there was nothing they could do.

Killed in the accident Thursday were Dr. John Mislow, 39, of Newton, Massachusetts, and Dr. Andrew Swanson, age 36, of Minneapolis, Minnesota. While part of the fall was observed by other climbers on the mountain, park officials say many factors remain unknown about the accident, such as the location where the initial fall occurred and whether the team was ascending or descending at the time.

Although the onset of the fall was not witnessed, a team did observe them falling between the 16,500-foot elevation on the Messner Couloir and its base at 14,500 feet.

Park rangers at the 14,200-foot camp were notified via FRS radio within minutes of the event, which occurred shortly before 2:00 p.m. on Thursday. Three skiers in the vicinity were first to respond to the climbers, who were located approximately 30 minutes away from the 14,200-foot camp. A team of four volunteer NPS rangers, including an emergency room nurse and two medics, followed close behind and confirmed that the two men had died in the fall.

The bodies were recovered by the park’s A-Star B3 helicopter that same evening and flown to Talkeetna.

The two men began an ascent of the West Rib route on May 30, and their climbing registration forms did not specify a particular descent route. Situated in between the West Rib and the West Buttress routes, the Messner Couloir is a steep, hourglass-shaped snow gully that drops from near Archdeacon’s Tower at 19,000 feet down to the 14,200-foot basin. With a 40- to 50-degree snow and ice slope, the Messner Couloir is an occasional advanced ski descent route, but is rarely descended on foot or ascended.

Drs. Mislow and Swanson were both experienced mountaineers. In 2000, Denali National Park and Preserve presented the two men with the Denali Pro Award, an honor recognizing the highest standards in the sport for safety, self-sufficiency, and assisting fellow mountaineers.

During their 2000 attempt of the West Rib route they aided several different teams in distress; assisted a National Park Service patrol with multiple visitor protection projects; and demonstrated sound risk assessment in their climbing objectives.


I came across this site searching for information about my childhood art teacher, John's grandmother I believe.
My hope was to get in touch with John's mother I met only a few times many years ago.
I am shocked and sad for both men's families. My heart goes out to his family.

This is just not right. Andrew, you were a good kid in school and a great man in life. I am sorry you are gone, the world is a worse place without you.

Simply a wonderful young man! He did so much and gave so much, but fortunately lived his all too brief life to the full. I am so saddened by his tragic death. My heart goes out to all he touched and were touched by him. To his closest family and friends my condolences. Andrew will be sorely missed and long remembered.

My heart goes out to their families. No matter how much you train and prepare accidents can still happen. Both John and Andrew seemed like very responsible and seasoned individuals.

Lauren, for many, pushing the edge a little bit heightens the intensity and beauty of life. From all accounts, these two gentlemen were highly skilled climbers and very analytical in their approach. Accidents can happen anywhere, from crossing the street to climbing a mountain. While their deaths were truly tragic and unfortunate, they were doing what they loved.

That is so sad! Why do good people put themselves into dangerous situations when they have wonderful lives & wonderful loved ones??

That is so sad!!

I saw Dr. Swanson four times in my life and I have been so distraught over this tragedy. Why do the good have to die young?

He saw me in November and indicated I should have a laminectomy. We were to set a date soon. However, my pain became so intense that I could not walk nor function. I went to see him on Thursday, November 13 and he took one look at me and said he was aware of what I was going through and he was just so sorry but he was leaving for Ghana Saturday morning. The more he talked to me and watched me, he apparently decided this surgery might still be doable. He called his nurse and asked her to try to get an operating room the next day and if so, she needed to cancel certain appointments in the office; she was able to make all the arrangements and I was in the OR under anesthesia when he came in and did a perfect surgery. He came to my room about 7:00 that evening and told me all was well. And it was. I had no pain AT ALL. He went to Ghana on Saturday and I saw him for followup in a week or so. I was well.

I have never had a doctor go out of his way for me like that (and I'm 70 years old). It was so touching to see him make the decision to perform surgery despite his very busy schedule. You can be sure that I have talked about his great kindness to me to many people. He really went the extra mile. The more I read and hear about him, it seems that was his way of life. What a wonderful gift.

I can only offer his family and friends my deepest condolences. As I indicated, I only knew him professionally for a short time but I have been in shock and pain for this young man who had to leave this world too soon.
