About this map

The Rio Grande National Forest dominates this mid-1960s landscape, where high-altitude peaks meet the edge of the San Luis Valley. This survey reveals a transition from the agricultural lowlands of the King Ranch and the settlement at Piedmont to the dramatic drainage systems of Zapata Creek and Urraca Creek. Local history is anchored by the Pioneer Urraca Cem, while the industrial past is marked by the Swab Mine tucked into the mountain slopes.

Water management is central to the area's development, evidenced by the Holbrook Creek Dam, Tobin Creek Dam, and the Garland Ditch. The survey captures numerous high-mountain water bodies including Lake Como, Blue Lakes, and Little Bear Lake, accessible only via a network of Jeep Trails and Pack Trails. Notable natural landmarks such as Zapata Falls and the eponymous Twin Peaks provide clear geographic orientation for the border between Alamosa and Costilla counties.
