Rosie grew up in the lakes of Minnesota. Sailing, windsurfing, waterskiing, you name it. If there was a way to spend time on the water, she was doing it. Her passion for frozen water was just as intense. Her parents met teaching skiing so it was inevitable that she would end up in the snow. She began ski racing and that would carry her to mountains across the world. She was always looking past the gates into the surrounding peaks - looking for lines and ways to explore. When her racing career ended, she wasted no time finding new ways to explore the mountains through climbing and backcountry skiing. More recently, ski mountaineering has come to be a priority in her recreational endeavors. In the summers, she is also an aspiring kayaker and rock climber. She is always up for a challenge and a good sunrise dance party. In the winters she is based out of Bozeman, MT and is a Ski Patroller at Big Sky. When she is not playing in the mountains or on the river you can find her reading a good book, covered in flour from baking experiments, or tending her garden.

I hope climbers are able to find a new appreciation for the mountains that we are fortunate enough to get to play in.

Mountaineering
At 20,310 feet, Mt. McKinley is the highest peak in North America and one of the most serious high-altitude objectives on the planet. The West Buttress is the standard route to the summit, and while it involves no technical rock or vertical ice climbing, that framing undersells the challenge. Miles of glaciated terrain, extreme cold, sustained altitude above 14,000 feet, and weather that can pin a team for days at a stretch are what define this climb. Above 15,000 feet the route steepens considerably, with fixed ropes on the most exposed sections. This is an expedition in every meaningful sense of the word.
Unlike most guide services operating on Mt. McKinley, RMI does not set a fixed end date for this program. The schedule moves with the mountain: conditions, acclimatization progress, and team readiness determine when the team pushes higher and when it waits. That flexibility is not a convenience; it is the approach that gives climbers the best realistic chance at the summit. Guides monitor performance and altitude response throughout, adjusting pace and plans as the situation demands rather than against an arbitrary calendar.
The West Buttress Expedition is a major commitment of time, fitness, and preparation. Climbers should expect to be on the mountain for three weeks or more and should arrive ready for the full weight of that. The mountain sets the terms here, and the program is built around accepting that.
