1957 Map of Mc Henrys Peak

About this map

The Continental Divide winds through this high-altitude landscape, marking the hydrological split between the Grand and Larimer county lines. Within the heart of Rocky Mountain National Park, the 1957 field survey reveals a terrain defined by active ice and water, from the Sprague Glacier and Tyndall Glacier to the headwaters of the Big Thompson River. The map captures the infrastructure of early park management and recreation, including the Patrol Cabin near Hayden Spire and the Ranger Station situated east of Dream Lake. Transportation through this vertical environment is limited to significant footpaths like the Bighorn Ditch Trail and the Tonahutu Creek Trail, alongside the notable Trail Ridge Road carving through the northern heights. Glacial features like the Bierstadt Moraine and the isolated Andrews Glacier reflect the geological forces still visible in the mid-century wilderness.
