1967 Map of Terrace Reservoir

About this map

La Jara Reservoir and Terrace Reservoir anchor this landscape within the Rio Grande National Forest, illustrating the vital water management systems of high-altitude Colorado. The presence of Shawcroft Cow Camp and Baxter and Martin Cow Camp points to the seasonal grazing patterns central to the regional economy during the late 1960s. High country movement is further evidenced by the Stock Driveway north of the Alamosa River and various Jeep Trails that traverse the complex network of canyons and ridges. Between the water bodies, the terrain is deeply incised by drainages like Hot Creek and Piedrosa Creek, with landmarks such as Bald Ridge and Jacobs Hill rising above the timbered slopes. This 1967 field-checked survey provides a precise record of these livestock outposts and the natural hydrology of the San Juan Mountains before later developments altered the backcountry character.
