About this map

Longmont and its surrounding agricultural landscape are defined by an intricate network of irrigation systems, reflecting a century-long history of water management on the Front Range. Notable waterways like the Highland Ditch, Rough and Ready Ditch, and Oligarchy Ditch snake across the terrain, feeding numerous reservoirs including Calkins Lake, Highland Lake, and Divide Reservoir. These systems support a cluster of outlying settlements such as Highland, Mead, and Liberty.

Genealogists and local historians can find significant landmarks across the quadrangle, including Highland Cemetery, Mountain View Cemetery, and Burlington Cemetery. The map also captures the area's industrial and social infrastructure, from the Helmer Brothers Pit and Cartwheel Airport to the Midwest Childrens Home. The presence of E County Line Rd marks the administrative boundary of Boulder County, framing the steady outward growth of the city.
