1966 Map of Boulder

About this map

Boulder and the surrounding Front Range foothills are shown at a point of significant transition, with purple-tinted revisions from 1978 highlighting the rapid expansion of the city's urban footprint. The street grid is densely detailed from Baseline Road north toward Linden Ave, anchored by the expansive campus of the University of Colorado. To the west, the rugged topography is dotted with historical mining sites like the Poorman Mine and Red Sign Mine, along with numerous small settlements such as Jamestown and Salina that trace the path of Fourmile Creek and Left Hand Creek. The map documents a blend of academic, industrial, and recreational land use, featuring the Boulder Mountain Park and the specialized scientific infrastructure of the Radio Telescopes near Mesa Reservoir.
