About this map

The South Platte River corridor north of Denver serves as a massive industrial and transportation hub in this late 1930s survey. Heavily urbanized districts like Globeville, Argo, and Utah Junction are defined by a complex grid of rail lines, including the Union Pacific and the Colorado and Southern. The presence of the massive Stockyards and a prominent Slag Dump along the river highlights the area's role in the region's agricultural and mineral processing economy.

Away from the industrial core, the map reveals early aviation infrastructure at the Denver City and Co Airport and the Municipal Airport. Smaller agricultural communities such as Welby, Adams City, and Derby are interconnected by irrigation features like the Fulton Ditch and the O'Brien Ditch. Institutional landmarks including Clayton College and the Riverside Cemetery provide significant points of interest for genealogists and local historians.
