1967 Map of Medano Pass

About this map

Medano Pass serves as the central high-altitude crossing on this mid-century survey, dividing the high country between the Rio Grande National Forest and San Isabel National Forest. To the west, the landscape transitions into the distinctive eastern margins of the Great Sand Dunes National Monument, where Medano Creek and Little Medano Creek descend from the peaks toward the valley floor. The map records a wilderness area defined by complex drainage systems like Poison Canyon and Big South Canyon.
