1957 Map of Trail Ridge

About this map

Trail Ridge Road serves as the central spine of this high-altitude landscape, tracing the crest of the Mummy Range through Rocky Mountain National Park. The map documents the intricate alpine drainage systems where the Cache la Poudre River begins its descent near Marmot Point. To the east, the terrain transitions into the broader glacial meadows of Horseshoe Park, fed by the confluence of the Roaring River and Fall River.
