Crowell Hilaka, in Richfield, Ohio, is the former estate of inventor Jim Kirby. During the 1920s, Kirby constructed a patented lake, a mill to generate electric power, a house air-conditioned with spring water, and a dance hall built on springs all of which are still there. Not only are they historically interesting, they are inspiring examples of engineering accomplishment in a beautiful, natural setting.

Operated as a Girl Scout camp for over 70 years, the property is now being sold. Friends of Crowell Hilaka ( FoCH ) seeks to preserve this land and open it to the public as a recreational and educational destination.
