About this map

Lake San Cristobal dominates the center of this high-elevation Colorado landscape, situated along the Gunnison River and the Slumgullion Creek drainage. The mapping reveals a terrain shaped by geology and extraction, featuring the massive Slumgullion Slide and various unnamed Mines and a specific Mine tucked into the mountain gulches. Human presence is marked by scattered infrastructure including a Radio Tower, a Landing Strip near Castle Lakes, and a small Cem overlooking the river valley.

The boundary of the Continental Divide winds through the southern portion of the sheet, separating the Gunnison National Forest from the Rio Grande National Forest. These high peaks, such as Red Mtn and Grassy Mountain, are accessible only via a network of a Jeep Trail and a Pack Trail, emphasizing the area's isolation in the mid-1960s. Water features like Argenta Falls and Alpine Gulch suggest a landscape defined by dramatic vertical relief and seasonal runoff.
