With RMI
Liam has been skiing since before he could pronounce his s’s and climbing anything that wouldn’t get him in trouble not too long after. However, it wasn’t until his family moved to Jackson, Wyoming when he was 13 years old that he really fell in love with the adventure of the mountains. Since then he’s become addicted to all the forms of movement that the mountains demand and found his deepest passion in exploring the vertical world. When he’s not out skiing or climbing he can typically be found frantically trying to figure out what his next adventure will be.

Mountaineering
The Four Day Rainier Climb is the classic route to the summit of Mount Rainier and the most common path climbers take into high-altitude mountaineering, following the standard south-side routes through glaciated terrain to one of North America's most recognizable peaks. It's a serious alpine objective that rewards preparation, fitness, and focus — for many climbers, the moment mountaineering becomes real, yet still within reach of well-prepared first-timers. Being able to say "I've been on top of that" while driving I-5 or flying out of Sea-Tac is an incredible achievement.
The climb begins with a half day orientation at BaseCamp, followed by a full day of mountaineering school on the mountain, then ascends to Camp Muir, where teams stay in the private hut RMI uses — the only guide service with its own shelter at Camp Muir. Throughout, you climb in small rope teams at a 2:1 climber-to-guide ratio — closer instruction, steadier pacing, and more attention on summit day. Before and after, your team is based at Rainier BaseCamp in Ashford, home to the BaseCamp Bar & Grill, Whittaker Mountaineering, and Whittaker's Bunkhouse.
