Actually, he’s hyped on whatever the day’s goal is, even if it’s a so-called ‘lesser’ peak that he’s climbed a hundred times.” He may be the first person to do certain things, and he’s set a high bar, but we don’t really talk about that. “He’s not self-aggrandizing about his climbing. “What he’s done is nuts, but he won’t advertise those accomplishments, short of sending me the occasional cool photo from a mountain top,” says Matt Holloway, an accomplished local climber who first met Robertson in 2003 while living in Babb. He’s likely the first person to accomplish the feat, but Robertson, 42, isn’t known for broadcasting his climbing achievements.

He’s climbed them all, including Glacier’s six highest summits in winter, deploying a mix of rock, ice and ski-mountaineering techniques to ascend and descend Cleveland, Kintla, Merritt, Jackson, Stimson, and Siyeh, all of which loom above 10,000 feet in elevation.

In 1996, as a newly minted high school graduate, Robertson moved from Great Falls to East Glacier, where he quickly discovered that the summits were indeed attainable, as are all of the park’s 234 peaks listed by the Glacier Mountaineering Society, including its five “technical-only” climbs.
