1971 Map of Hayden

South of the river valley, the topography rises into a series of deeply eroded drainages such as Smuin Gulch, Stokes Gulch, and Dry Gulch. Private water storage is prominent here, with named features like Emrich Reservoir and John C Temple Reservoir No 1 appearing near the various mines and gravel pits that underscore the local extractive industry. This survey documents the intersection of rail transport, river access, and agricultural infrastructure during a period of steady development in northwestern Colorado.
