Situated on the Continental Divide at an elevation of 11,500 feet, the location provided favorable conditions for studies of the solar corona due to reduced atmospheric scattering. The Climax Molybdenum Company donated the land for the Observatory, as well as funds for constructing buildings and a $6,000 grant. Roberts was the sole resident scientist at the isolated mountain Observatory, and he and his wife Janet remained the only residents in the early years. During World War II, coronagraph observations of solar activity made by Walter Roberts at Climax had important implications for wartime communication over long distances. The relationship between sun weather and radio transmissions was used by the U.S. military in predicting favorable times for scheduling large-scale military operations that depended on good radio communications. After the war, the Climax station became the first scientific corporation, the High Altitude Observatory of Harvard University and the University of Colorado. HAO's administrative offices and Roberts moved to Boulder. The Observatory moved in 1952 to a new location three miles north of the town of Climax, where a new larger dome was built. In 1960, the High Altitude Observatory became a research division of NCAR. The Climax Observatory would serve as NCAR’s high altitude site for solar research for 31 years, closing in July 1972 as the observing facilities at Climax had gradually became non-competitive with more modern observatories due to the increasingly demanding requirements of solar research programs. spase://SMWG/Person/UNKNOWN GeneralContact Climax Observatory Homepage https://www.archives.ucar.edu/exhibits/hao/facilities/climax-observatory Detailed information about the Climax observatory.
