In 1912, a group of 25 mountain enthusiasts founded Colorado Mountain Club (CMC). The group included several prominent naturalists, such as Enos Mills, who helped found Rocky Mountain National Park; Roger Toll, who was superintendent of Yellowstone, Rocky Mountain, and Mount Rainier National Parks; and Carl Blaurock, who climbed all of Colorado’s 14,000-foot peaks. The club's first members volunteered at schools and advocated for environmental issues, aiming to raise awareness about the Colorado mountains through art, science, literature, and recreation, and seeking to preserve the alpine region.
Today, CMC continues to challenge its members and the community with a variety of events ranging from adventure travel and service projects to concerts and educational lectures. School groups participate in mountain-climbing field trips, and members network at annual dinners and outdoor excursions. The club's adventure trips explore the greatest natural sites of the world, taking participants up the slopes of Kilimanjaro, down the rapids of the Colorado River in the Grand Canyon, and through the historical cities of Russia.
