Mount Logan

Hi all,
We just finished guiding a successful ascent of Mount Logan spanning 21 days from May 16 to June 6, 2026.
Our 2 groups of 4, ascended Canada’s highest peak on skis via the King Trench route and summited on June 2nd and June 3rd respectively. We reached basecamp from the Silver City airstrip in Yukon with the Pilatus ski plane from Icefields Discovery. Lucky for us, we were able to fly in and out as per our planned itineraries. During our expedition, we traveled from 2750m to 5960m on the Quintino Sella Glacier, King Trench, Prospector Col and Summit Plateau areas on route to the main summit.
Late-spring transitional weather pattern prevailed across the St-Elias Mountains, with cool temperatures, extensive remaining snowpack at mid and high elevations, and a mix of clouds and intermittent precipitation. The alpine environment remained firmly in winter-like conditions persisting on glaciers and high peaks. Overall, I would say it was colder and windier than many previous trips here at similar time. Temperatures varied from -30C overnight to -15C during the day.
Despite the weather pattern, we progressed upwards close to our scheduled itinerary. We endured a severe windstorm at camp 1 (3300m) that nearly destroyed our tents and snow walls. After a quick reset, we continued and reached camp 2/King Col (4100m) on May 23rd and camp 3/football field (4900m) by May 27th where we endured several small storms while acclimatizing and build red blood cells! On May 31st, a marked improvement in the weather allowed us to move to a jump camp at 5250m just below the south side of Prospector col. The following day, June 1st, we moved our camp to the summit plateau (5100m) via the Prospector Col (5520m) in with out but warmer conditions. This is when we entered our first warming trend of the trip. Favorable weather conditions with minimal winds allowed us to summit on June 2nd and June 3rd respectively. We then started our descent the following days.
Traveling conditions, snow coverage and crevasses were generally excellent this year. Snowpack depth on glaciers was greater than 250cm and increased with elevation. Thinner snowpack areas were observed in some wind exposed locations. The crevasses and snow bridges above the King Col headwall (4200m) felt less spicy and intuitive, generally more manageable then in previous years. Similarly, the crevasses and tension areas immediately below the Football Field (around 4800m) were well covered and easy to navigate this year. That said, the Queen Peak icefall (4550m) was more like the Kumbu icefall this year. A large, climax like, serac release occurring about a moth prior covered roughly 150m of the entire normal route. This required us to navigate through an area of fresh ice debris. On a positive note, the crevasses in this area were easier to negotiate then in previous years.
Gear wise, we used ski crampons, boot crampons and ices axe in specific locations. Ski crampons were useful for ascending above King Col early in the mornings. They were also very useful for ascending to last few meters to Prospector Col. Boot crampons & ice axe were used to tackle the final steep slope and ridge walk to the main summit where good cramponing on varied firm surfaces lead to the summit. We believe our success is directly related to adequate group fitness, perceverence, and decent mountain conditions on the route. That said, our ascent progression (carry high & sleep low) while taking strategic rest days certainly contributed to it. In the end, it seems as though patience and determination were almost as important as fitness and weather factors.
Feeling lucky to have had the opportunity to guide yet another great group of folks up Canada’s highest peak!
Cheers,
David Lussier & Max Darrah
