Wow, 8%!  But that’s going start improving dramatically, Dave estimated about 100 climbers went to the summit yesterday…with more to come in this stretch of fine weather.

Ranger Update

NPS Denali (14K) Patrol #2 (Corn + 5 VIPs)  Yesterday afternoon’s trip to 17K was just an acclimatization run, but the patrol moved to high camp today. They intend to spend several nights at 17K addressing some high camp duties, inspecting fixed lines and pickets, inventorying the 17K rescue cache…and importantly, being poised to respond to any climbers in need on the upper mountain.

NPS Denali (14K) Patrol #3 (Weber + 5 VIPs)  Dave and VIP Shane were up most of the night assisting a couple climbers with altitude related illnesses. Prime weather has resulted in a big push on the upper mountain yesterday.

NPS Basecamp (7K) Patrol #3 (Reichert + 2 VIPs) With good weather comes a lot of Basecamp comings-and-goings to support. Finally there are climbers starting to head out of the Range with happier summit stories to tell.

NPS Denali (14K) Patrol #4 (Westman + 5 VIPs)  The team camped at 9,500-feet last night.

Route Conditions


For several years now, NPS rangers have noted a growing trend in the numbers of climbers opting for a long summit push from 14,200-foot camp, as opposed to the traditional push from 17,200 feet. Yesterday, an estimated 20 to 30 climbers left 14K with intentions of one long day to the summit and back.  NPS Rangers caution climbers that this single push strategy limits one’s ability to be self-sufficient and can increase the margin of error exponentially. Factors to consider include:

>  Travelling light means you are carrying limited emergency gear;
>  Without an established camp at 17,200-feet, there are limited options in terms of places to retreat to in a storm/illness/unexpected situation;
>  The feat is often a much more significant undertaking than climbers expect;
>  Don’t forget to factor in wait times on the fixed lines and other bottlenecks during the height of the season – this can often add hours to an already long and exhausting day at altitude.

Ranger Dave Weber and his team of volunteers assisted and treated at least 3 climbers who requested help of some variety either during or after an exhausting single push from 14,200 feet yeseterday. An extended day at altitude spurred signs and symptoms of HACE, HAPE, and some cases of minor frostbite.  Always be self-sufficient — its not appropriate to rely on other climbers who are camped at 17,200 feet!
