1958 Map of Fall River Pass

About this map

Lulu City (Site) sits near the headwaters of the Colorado River, a reminder of the short-lived silver mining boom that once occupied this high mountain valley. This 1958 survey captures the intricate water management infrastructure of the era, including the Grand Ditch and Upper Michigan Ditch, which divert water across the Continental Divide to the eastern plains. The landscape is dominated by the massive presence of Specimen Mountain and Jackstraw Mountain, with tourism-era infrastructure like the Phantom Valley Trading Post and Milner Pass Road Camp supporting travel along the Trail Ridge Road. Numerous high-altitude lakes, including Iceberg Lake and Poudre Lake, are documented alongside the La Poudre Pass Ranger Station, marking the intersection of conservation, recreation, and early industrial water rights.
