After years of attempts, two brothers succeeded on the probable first winter ascent of Glacier National Park’s highest peak. Josh and Isaac Mohler summited 10,466-foot Mount Cleveland on March 7 during a four-day round trip. It was Josh Mohler’s fourth attempt in winter. Mount Cleveland is not technically difficult, with fourth-class rock and steep snow, but it is extremely remote (22 miles from the road) and subject to severe weather. “Every other time, we made it to basecamp ... and then sat there in a whiteout or a blizzard," Mohler told the Great Falls Tribune. “Three years ago, we woke up to rain at 2 a.m. at 7,000 feet. That was epic.” The peak also can hold severe avalanche danger. In 1969, five men were killed in an avalanche while attempting Mount Cleveland in winter. This was the deadliest avalanche in U.S. history at the time and was the subject of a book, The White Death.
