1958 Map of Fall River Pass

About this map

Lulu City remains a quiet marker of the late nineteenth-century silver boom within the Kawuneeche Valley, where the headwaters of the Colorado River begin their long journey. This 1958 survey, updated with 1970s revisions, highlights the high-altitude wilderness where the Continental Divide separates the drainage of the Cache la Poudre River and the Big Thompson River. The landscape is defined by its early administrative presence, from the La Poudre Pass Ranger Station to the Fall River Pass Visitor Center Ranger Station. Notable geologic and topographic features like Little Yellowstone, The Crater, and Specimen Mountain are documented alongside the recreational infrastructure of the era, including the Ute Trail, Thunder Pass Trail, and the winding Tundra Curves. This map captures the region after decades of forest management, showing the boundaries between Rocky Mountain National Park and the adjacent Roosevelt National Forest.
