Platteville and Milliken anchor this 2016 study of the agricultural corridor north of Denver, where the South Platte River dictates the landscape's complex irrigation network. This high-plains region is defined by an intricate system of man-made waterways including the Farmers Independent Ditch, Spear Canal, and Platteville Ditch, which redirect water across the section lines to support the surrounding farmland. The map provides significant detail for local history, marking the small settlement of Vollmar and aviation sites like Tonga Airport. Genealogical interest is found at Mizpah Cem and Saint Francis Cem, while larger-scale water management is evident through the Mose Davis Reservoir Number 2 and the Twombly Reservoir. The rigid grid of county roads, such as Co RD 36 and Co RD 34, contrasts with the meandering riverbed, illustrating the long-term intersection of natural hydrology and systematic land development.
