1966 Map of Thirteenmile Creek

Remote livestock management and early resource extraction define the local economy of the late 1960s. The map traces the Stock Driveway and multiple Gravel Pits, alongside access routes like the Hay Flat Trail. These features suggest a working landscape utilized by ranchers and industrial surveyors, particularly in the vicinity of Piceance Creek and Thirteenmile Ridge, where the terrain transitions toward White River Mountain.
