About this map

Louisville and Superior serve as the primary hubs in this mid-century survey of Boulder County, which captures the region's transition from a coal-dependent economy to a landscape shaped by water management. The area is heavily marked by its industrial heritage, with numerous coal workings such as the Crown Mine, New Red Ash Mine, and the Industrial Mine (Aban'd) dotting the terrain between Davidson Mesa and Shanahan Hill. Many of these sites, including the Cracker Jack Mine, reflect the fading coal era as mines were listed as inactive or abandoned by 1950.

A complex network of irrigation and water storage infrastructure, including the Goodhue Ditch, Community Ditch, and Great Western Reservoir, underscores the vital importance of water to the Boulder Valley. Local life centers on landmarks like the Sacred Heart Ch, Marshallville Sch, and the Superior Cemetery, providing essential coordinates for genealogical research. The CB&Q railroad connects these settlements, illustrating the transport corridors that once moved both coal and commuters through the foothills.
