2019 Map of Medano Pass

About this map

Medano Pass serves as a critical geographic transition point between the high mountains and the expansive dunefields of southern Colorado. This 2019 survey captures the convergence of the San Isabel National Forest, Great Sand Dunes National Preserve, and Great Sand Dunes National Park. The landscape is defined by high peaks like Mt Herard and Mt Zwischen, with drainage patterns including the intricate headwaters of Medano Cr and its tributaries. Human engineering is visible through the presence of the Hudson Ditch and Medano Ditch, reflecting water management efforts in this high-elevation environment. Access to the interior is documented via the Medano Lake Trail and the Sand Ramp Trail, while the surrounding terrain is deeply incised by notable landforms such as Big South Canyon and Sawmill Canyon.
