1957 Map of Bottle Pass

About this map

Arapaho National Forest dominates this high-altitude landscape in Grand County, Colorado, defined by sharp ridgelines and the critical management of alpine water resources during the late 1950s. The map illustrates an intricate system of water diversion, including the Big Six Ditch and the St Louis Aqueduct, which channel runoff from the slopes of Blue Ridge and Byers Peak. These engineering features highlight the importance of the Continental Divide's western slope to downstream water users.
