Minnesota Climber Thwarted From Winter Ascent of Alaska's Mount McKinley for Third Time

Once more, the weather gods have driven Minnesota adventurer Lonnie Dupre back from the 20,320-foot summit of Mount McKinley. Dupre had hoped to this year become the first climber to solo the mountain in January, the cold heart of the Alaska winter. It was his third try; twice before the wind and cold had turned him back. He was optimistic this year as the weather cooperated on the long, uphill slog from the Kahiltna Glacier landing strip near 7,200 feet to where the 14,200-foot camp sits during the normal May to July climbing season.

All of that changed late last week. The thermometer dove and the winds came up. On his first attempt to go from 14,200 to high camp at 17,200 last week, he made it only to 15,200, where he cached gear before retreating. He made high camp on Friday, but found it impossible to dig in there. He spent a cold night with little shelter, his website reported.

"...Extremely hard snow made it impossible to build a safe snow cave at 17,200, and instead of getting much-needed rest, he spent the entire night trying to keep the cave -- and himself -- warm," it said. "When he called his base camp at 4 a.m. on January 27, it was -35 degrees F in the snow cave."

Considering a Monday forecast for winds of 60 to 70 mph in 20-degrees-below-zero cold, Dupre decided it best to retreat. Winds of that strength can blow a man clear off the summit ridge.

"It was virtually a life-or-death decision for Dupre," the website reported. "Even if he had made the summit (Sunday), which would have meant a 12-hour or more travel day between 17,200 and the summit and back, he knew he would not have had the energy or means to survive back at the 17,200 camp ...
