1958 Map of Fall River Pass

About this map

The Kawuneeche Valley serves as a central corridor for the headwaters of the Colorado River in this late 1950s survey. The landscape is defined by the high-altitude engineering of the Grand Ditch, which skirts the slopes of Mount Neota and Thunder Mountain to divert water across the Continental Divide. Cultural markers of the era include the Phantom Valley Ranch and the nearby Phantom Valley Trading Post, reflecting the mid-century transition of the area into a premier destination for mountain recreation. Evidence of earlier mining and logging history remains visible through the Lulu City (Site) and a Sawmill in Skeleton Gulch. The map meticulously tracks the winding paths of Tundra Curves and Medicine Bow Curve, highlighting the complex road engineering required to navigate the passes between the Roosevelt National Forest and Rocky Mountain National Park.
