USGS Topo · Published 1969About this map
Coal mining operations and intensive agricultural irrigation define this section of Weld County as it appeared at mid-century. A cluster of settlements including Firestone, Frederick, and Dacono are concentrated along the Union Pacific railroad line, showing a landscape built on the extraction of coal. This industrial focus is evidenced by the numerous named shafts and pits scattered across the quadrangle, such as the Shamrock Mine, Boulder Valley Mine, and Imperial Mine, as well as the State Coal Mine Junction.
