Carol Kotchek

Carol Kotchek moved from Ketchum/Sun Valley, Idaho to Boulder, Colorado in 2003. The reason for this move was to be in the heart of the vibrant Boulder climbing scene.

Once established in Colorado, Carol obtained a bachelors degree in accounting. Combining career with passion, Carol was hired by the American Alpine Club as their accountant and worked in that role for ten years. Besides being their accountant, Carol had the opportunity to organize and lead events for the AAC such as the International Climbers Meet held every year in Yosemite Valley. At this event climbers from all over the USA and the World would convene in Yosemite Valley for a week of climbing, clinics, and sharing their passion of the sport. She was also the Front Range Section Chair for the AAC and had the opportunity to manage the opening event for Earth Treks, Golden, a very memorable experience. Carol’s passion is technical rock climbing. She had her 15 minutes of fame as the cover girl on the City of Rocks, Idaho guidebook and still gets a shout out in the most recent guidebook for that area. She’s also been involved in many local climbing organizations such as the Flat Irons Climbing Council, the Boulder Climbing Community, and the City of Rocks Climbing Management Plan. More than just the act of climbing, she takes pride in being an influencer on the management of climbing areas for future generations.
