1970 Map of Frisco

About this map

Dillon Reservoir dominates this high-altitude landscape, its waters having altered the local geography as a primary feature of the Denver water system. The map captures the town of Frisco during a period of transition, showing the infrastructure of the newly established Swan Mountain Recreation Area and the U S Air Force Recreation Area alongside older mining-era remnants. To the south, the site of Masontown and the presence of a dredge on the Blue River near Braddock Flats point to the area's rich mineral history and the industrial-scale gold extraction that once reshaped the river valley.
