Guide: Washington, Alaska
Bobby Cosker

“Your comfort zone is a beautiful place, but nothing grows there.” – GM.

Originally from New England, Bobby moved to Utah in 2007 to immerse himself in the bigger mountains of the West. Since then, he has climbed and guided across South America, Europe, the Canadian Rockies, and the U.S., with more than 40 expeditions in the Central Alaska Range. From 2015 to 2017, he also served as a VIP Climbing Ranger on Denali with the National Park Service, adding a rare level of depth and perspective to his knowledge of the Alaska Range, and his guiding expertise on Denali.

Today, Bobby follows the seasons, guiding and climbing in Utah and Ouray during the winter, and in Alaska and the Pacific Northwest through the summer. He is especially drawn to remote, exploratory alpine routes, and takes pride in sharing the lessons of the mountains with others. When he isn’t spearheading expeditions or tackling a personal objective, you’ll often find Bobby with a strong cup of coffee and a good book.
