1957 Map of Bottle Pass

About this map

Arapaho National Forest dominates this mid-century survey of the Colorado Front Range, revealing a landscape defined by high-altitude peaks and the early infrastructure of the Fraser Experimental Sta. The map captures a transition point between the primitive access of the Idlewild Trail and the emerging recreational and scientific use of the land. High peaks such as Ptarmigan Peak and Sheep Mountain are linked by topographic features like Bottle Pass, which serves as a natural corridor through the Continental Divide’s foothills.
