1957 Map of Berthoud Pass

About this map

Berthoud Pass serves as the central anchor of this mid-century survey, marking the high-altitude transit point where U.S. 40 crosses the Continental Divide at the border of Grand and Clear Creek counties. The map documents the early infrastructure of mountain recreation and resource management within the Arapaho National Forest, highlighting the Berthoud Pass Ski Area, the First Creek Ski Cabin, and the Mary Jane Ski Trail. Beyond recreation, the landscape is defined by its water and engineering history, featuring a complex network of names like Vasquez Creek and Little Vasquez Creek, alongside the subterranean Jones Pass Tunnel. High peaks such as Colorado Mines Peak, Vasquez Peak, and Stanley Mountain dominate the terrain, while signs of travel and utility are found in the Big Bend Picnic Grounds and several designated ditches and aqueducts.
