About this map

San Isabel National Forest and the eastern edge of Great Sand Dunes National Monument dominate this 1960s study of the high-altitude divide between Alamosa and Huerfano counties. The terrain is defined by a dense network of drainage systems feeding the Huerfano River, including North Zapata Creek and Cascade Creek. Human presence is marked by isolated outposts like the Singing River Ranch and infrastructure such as the Radio Tower near Mosca Pass.

A series of specialized pack trails, including the Lite Trail, Cascade Trail, and Strawberry Trail, navigate the steep slopes of Carbonate Mountain and Green Mountain. These routes, along with various jeep trails, suggest a landscape utilized for forestry and remote access rather than dense settlement. Water management is evident through several upland catchments like Montez Reservoir and Wilson Reservoir, which supported the region's agricultural and ranching interests during this era.
