Minnesota mountaineer Lonnie Dupre has apparently completed a solo summit of the 20,237-foot Mount McKinley in January, the first time anyone has accomplished such a feat, according to Stevie Plummer, Dupre's expedition manager.
It was Dupre's fourth attempt at a January solo summit. He arrived at base camp to begin his journey on Dec. 18.
On Dupre's Facebook page Sunday afternoon, an image showing Dupre's latitude and longitude based on a GPS tracker he was carrying with him was accompanied by the exclamation "SUMMIT!!!!!"
The image also included a message from the climber, which said, simply, "All OK, Doing Well."
