About this map

Longmont and its surrounding agricultural plains are depicted here during a period of significant urban expansion, as shown by the extensive purple revisions from the late 1970s. The landscape is defined by an intricate network of irrigation, with St Vrain Creek and Left Hand Creek feeding into numerous reservoirs such as Terry Lake and Calkins Lake (Union Reservoir). This water management system supported small outlying settlements like Highland and Liberty, which are shown alongside larger community institutions including the Mountain States Childrens Home.

Transportation and industry are anchored by the Great Western and Burlington Northern railroads. Local landmarks like the Grange Hall and the Drive-in Theater west of North Main Street reflect the mid-century social character of the area. For genealogists, the map identifies several burial sites, including the Burlington Cem and Highland Lake Cem, providing precise locations for family history research within the Boulder and Weld County border region.
