1957 Map of Trail Ridge

About this map

Rocky Mountain National Park is defined here by the high-elevation engineering of the Trail Ridge Road, reaching landmarks like Rock Cut and Iceberg Pass. This 1950s survey documents the transition from early pack trails to automotive tourism, showing the Old Fall River Road and the Ute Trail winding through the Mummy Range. Along the glacial terrain of Hanging Valley and Hidden Valley, the map captures specific recreational and utility infrastructure, including the Hidden Valley Ski Area complete with a Sky Lift and Ski Lodge, alongside a Power Plant on the Big Thompson River. For those researching mid-century park management, the map identifies a Ranger Sta and Patrol Cabin near Willow Park, providing a record of the park's operational footprint before later modernization.
