Bigtree Posted October 22, 2007 Share Posted October 22, 2007 Am thinking about climbing Denali next year via west buttress to celebrate my 45th year on earth. Will likely rely on the guiding services of AAI based out of Bellingham given my past positive experience with them years ago; however, I'm slightly mystified that their "season" is May 4 - July 5th which seems awfully short (ref. http://www.mtnguide.com/ProgramDetail.asp?program=9 ). Does anyone know if this is the norm with guiding services up there or is there something else in play? Surely the route is quite doable throughout July and August, no?

Tons of info. Hope this helps some. Quote Link to comment Share on other sites More sharing options...
wfinley Posted October 22, 2007 Share Posted October 22, 2007 All the guides services are off by early July. The crevasses start to get nasty in late June... the latest the peak has been climbed was late July by a crazy Russian who later came back to climb it in late December - thus holding both the latest summer ascent record and the earliest winter ascent record.

Climzalot Posted October 22, 2007 Share Posted October 22, 2007 (edited) Hi Bigtree. The climbing season on Denali is dictated by a number of factors, weather and glacier conditions being the two most relevant. Prior to early May, most of the mountain is still very much in "winter" condition and the summit is often poking into the jetstream, making high camp and the summit very uncomfortable, if not deadly places to be. In general, the weather tends to be a little better at lower elevations in May than in June, but the winds on average are higher. Wind is a huge factor, perhaps the biggest, in one's ability to summit on any high and cold peak. In June, the temps warm up a bit, but precipitation/visibility are larger issues. I think the ideal time to plan an expedition to Denali is shooting for a departure in late may or early June. According to the Park service stats, June is the busiest month on Denali and June 15th is day on which the most people reach the summit. A summit day of 6/15 means that those folks would have started around the last week in May. The first teams to hit Denali usually start showing up in mid-April. The Park service base camp usually goes in towards the end of April (29th last year). The downside of going when weather and conditions are forecasted to be at their best, is that the mountain will be at it's busiest. Denali is a busy place. Knowing that ahead of time and setting expectations accordingly seems to diffuse the disappointment of most hoping for solitude. I think it is a super fun place to be and enjoy seeing lots of teams in action, making decisions, sharing food and stories along the way. Having good company and some international flavor adds a lot to the experience. Dealing with trashed campsites and bad attitude's certainly doesn't. Later into the season, glacier conditions, particularly on the lower Kahiltna, start to become much more problematic. The big factor here isn't necessarily climber's ability to negotiate and deal with such things, but more that the pilots become less able and willing to land at base camp and pick you up. Not too many folks are super keen on the 50+ mile walk down the glacier and back to the road! So, effectively, the climbing season is from May through the second week in July. Hope this helps a bit. I sent you a PM regarding the Alpine Institute's Denali program. Coley A rough day to be on the summit.

WCC Posted October 22, 2007 Share Posted October 22, 2007 Actually, Vin Hoeman climbed Mount McKinley in August in the late 1960s, so he has the latest summer ascent. However, significant warming has occurred since that time and you will have a tough time finding an aircraft to land on the Kahiltna Glacier after early July.

swaterfall Posted October 23, 2007 Share Posted October 23, 2007 If only we could land at the top of ski hill... Quote Link to comment Share on other sites More sharing options...
Alex Posted October 23, 2007 Share Posted October 23, 2007 Early May is bitter cold on the hill. By early July, the planes can no longer land in some spots due to the glaciers opening up. Hence the season advertised... Quote Link to comment Share on other sites More sharing options...
Bug Posted October 23, 2007 Share Posted October 23, 2007 I read a story about some folks doing an ascent up there in the early days. The plane was one of the first to use skiis. They landed on the glacier and when they came to a stop, the plane sunk intothe snow. They had to dig and jack and frantically work the plane around to a spot where it could get a start. It had a lot of trouble getting its speed up and droppedoff the end of a glacier and out of sight. It finally pulled up and circled and informed the climbers they were now on their own. It was a long hike out. Quote Link to comment Share on other sites More sharing options...
Bug Posted October 23, 2007 Share Posted October 23, 2007 When I was returning to N Kahiltna Base, we were hiking up the N Kahiltna and came over a rise to see a plane upside down and pointing uphill after an obvious flip. When we got up to the landing strip, we found out that it happened the day before in soft conditions. We were next in line when we got up there. One of the people who was in the plane when it flipped sat next to me. She was tense. The thumps as we bounced off the snow were REALLY hard. I was glad it was before noon. That was early June.

crmlla2007 Posted October 23, 2007 Share Posted October 23, 2007 As well, last I understood, the Park Service restricts the maximum altitude a plane can land on the glacier at - when the snow recedes above that limit they can no longer land. I talked to a friend of mine who ended up walking out in late July. Came out after a week of hiking and he and his partner were down to their last gummy bear.

Climzalot Posted October 23, 2007 Share Posted October 23, 2007 The NPS restriction on landing zones isn't based on altitude, but rather the National Park boundary. The landing zone on the SE Fork of the Kahiltna (Denali Base Camp) is just outside of the Park. Once you turn the corner at the bottom of Heartbreak Hill and starting heading up the main fork of the Kahiltna you are in the Park and planes can't legally land there unless asked to do for official business. The NPS Llama has largely negated the need for any fixed wing landings in the Park for rescue purposes. The only thing that shuts down the landing sites is snow/glacier conditions. Cracks start opening up at BC even in May some years. The landing site often slides up the glacier a bit even as the typical season progresses. On the first ascent of the W. Buttress, Washburn and the crew were dropped off at the base of Ski Hill (7800'), well within the Park and near where most people make camp 1 these days. I know there have been a few landings at 14K as well, but I couldn't tell you when and by who. Impressive. Quote Link to comment Share on other sites More sharing options...
BlackSheep Posted October 25, 2007 Share Posted October 25, 2007 I know there have been a few landings at 14K as well, but I couldn't tell you when and by who. Impressive. The Late Don Sheldon landed a few times at 14k for rescues. Its described in good detail in "Wager with the Wind" his biography. ( an excellent read for early Alaska range flying...) not sure if anyone else has landed there since... Quote Link to comment Share on other sites More sharing options...
Alex Posted October 25, 2007 Share Posted October 25, 2007 They landed a helo on the top of Sultana recently, though! Quote Link to comment Share on other sites More sharing options...
Climzalot Posted October 29, 2007 Share Posted October 29, 2007 Here is a photo of a Pavehawk just after it touched down on the summit of Mount Hunter. From time to time the military holds "trainings" in the Alaska Range where helo pilots practice their high altitude landing skills. Strange site and experience after a few days of solitude on a peak like Hunter. Quote Link to comment Share on other sites More sharing options...
