MINNEAPOLIS — A Minnesota adventurer has succeeded in becoming the first solo climber to reach the summit of Alaska’s Mount McKinley in the month of January, his support team said Monday, citing a GPS tracking device.

Lonnie Dupre, of Grand Marais, reached the 20,320-foot summit of North America’s tallest peak at 2:08 p.m. Alaska time Sunday, said project coordinator Stevie Plummer.

Dupre sent a text message saying “All OK, Doing Well,” through a SPOT GPS messenger device that showed it was sent from the same coordinates as McKinley’s summit.

Plummer then posted on the expedition website and on Dupre’s Facebook page a map generated by the SPOT system, which she said is “extremely accurate,” showing he had made it. She also said he sent a similar SPOT message about 3 1/2 hours later showing he had successfully descended to his high camp at 17,200 feet.

“He spent 10 minutes on the summit, took some photos, then he realized exactly how high up he was and decided to head back down. I guess reality struck at that moment,” Plummer said while en route to Alaska to meet up with Dupre.
