About this map

The Flatirons dominate the landscape southwest of Boulder, where the dramatic transition from the plains to the Front Range is meticulously documented during the early 1940s. The map illustrates a complex network of ranching and early mountain settlement, featuring Kossler Ranch and Walker Ranch alongside established community hubs like Chautauqua and the Green Mountain Cemetery. Water management for the growing region is evident through features like the South Boulder Creek Diversion Canal and the City Reservoir.

Industrial and educational footprints of the era are preserved in the locations of the Copeland Mine and several rural schoolhouses, including the Plainview Sch and the already Pine Grove Sch (abandoned). Transportation follows the winding course of the Denver and Salt Lake railroad, which cuts through the mountains near Crescent and Plainview, serving a landscape where the Coal Creek Store acted as a vital local landmark for those living along the creek beds.
