Mission Statement and Activities
Rocky Mountain Nature Association's purpose is to support research, interpretive and other educational programs of the National Park Service and allied public agencies. To accomplish these objectives the RMNA publishes, sells and distributes interpretive materials to the general public. It also conducts educational seminars each summer and offers membership in the RMNA to the general public. The profit from these activities enhances educational and research programs. In 1986 the RMNA created an allied nonprofit, the Rocky Mountain National Park Associates, which merged back into the RMNA December 1, 2005. It is currently known as the RMNP Fund and operates under the umbrella of the RMNA. The Fund raises money for significant long-term improvement projects within Rocky Mountain National Park including land acquisition, capital construction, restoration and preservation of historic structures, development of educational exhibits, construction of trails and development of wheelchair accessible pathways.
