The northern Colorado coalfields around Lafayette define this 1938 survey, revealing an industrial landscape where mining and agriculture met. Local coal production is evident through several named operations, including the Centennial Mine and the Monarch Mine, while the Chicago and Northwestern and Colorado and Southern railroads facilitate the transport of resources. The settlement of Coalton and the growing town of Broomfield are documented alongside numerous early irrigation and storage features like the Zang Reservoirs and Nissen Res No 1.
