1966 Map of Thirteenmile Creek

About this map

Grand Hogback dominates the central topography of this mid-century survey, forming a distinct geological spine through the northwestern Colorado wilderness. The landscape is defined by an intricate network of drainage basins including Thirteenmile Creek, Fourteenmile Creek, and Twelvemile Creek, all flowing through the White River National Forest. Human impact is visible through specialized land use, particularly the Stock Driveway in the southeast corner near Piceance Creek, reflecting the region's ranching heritage. Several named gulches like Moonlight and Camp Gulch cut through Corral Ridge, while various gravel pits and a network of Jeep Trails and Pack Trails suggest a territory shaped by resource extraction and remote access. The boundary between Rio Blanco and Garfield counties bisects the southern portion of the sheet, providing a precise reference for historical land ownership and administrative limits.
