Welcome to the Rocky Mountain Chapter of
The Explorers Club
We are 130 explorers and adventurers who are passionate about the advancement of field research and the ideal that it is vital to preserve the instinct to explore. Since its inception in 1904, the Club has served as a meeting point and unifying force for explorers and scientists worldwide.
Founded in New York City in 1904, The Explorers Club promotes the scientific exploration of land, sea, air and space by supporting research and education in the physical, natural, and biological sciences. The Club’s members have been responsible for an illustrious series of famous firsts: first to the North Pole, first to the South Pole, first to the summit of Mount Everest, first to the deepest point in the ocean, first to the surface of the Moon – all accomplished by our members.
The Club provides expedition resources including funding, online information, and member-to-member consultation. And our famed annual dinners honor accomplishments in exploration. But probably the most powerful resource available to those who join the Club is fellowship with other members—a global network of expertise, experience, technology, industry, and support.
The Explorers Club actively encourages public interest in exploration and the sciences through its public lectures program, publications, travel program, and other events. The Club also maintains Research Collections, including a library and map room, to preserve the history of the Club and to assist those interested and engaged in exploration and scientific research.
If you are located within the Rocky Mountain region from the Canadian to Mexican borders, you can learn more about joining by logging onto Explorers.org.
