Lonnie Dupre on the top of Denali

The Arctic explorer Lonnie Dupre has became the first person to to solo-summit Denali (Mount McKinley) in January. Dupre arrived at basecamp on the Kahiltna Glacier on 18th December and reached the summit on 11th January after spending nearly a month in extremely harsh winter conditions on the mountain.
With winds exceeding 100mph, temperatures plummeting below -60 degrees Fahrenheit and only 6 hours of sunlight per day, only nine previous expeditions totalling 16 climbers have reached the summit in winter.
Since winter 2011-2012, the American mountaineer has spent 60 days on this mountain, reaching a maximum of 5250 meters but had to give up due to bad weather. The first winter solo ascent was in 1988 by Vern Tejas but this is the first one in January, the must unconfortable month of the year.
Here an interesting document about the history of main events of Denali.
