About this map

Twin Peaks rises above the transition from the high San Luis Valley floor into the high elevations of the Rio Grande National Forest during the mid-1960s. This survey of the Sangre de Cristo Range captures a landscape defined by water management and mineral prospects, featuring isolated infrastructure like the Swab Mine and several water control points including the Tobin Creek Dam and Holbrook Creek Dam. The presence of the Pioneer Urraca Cem near Urraca Creek suggests the enduring legacy of early settlers in this high-altitude environment.

Agricultural activity and travel are documented through the King Ranch and the small settlement of Piedmont in the southwestern corner. Navigation across the steep terrain is marked by a network of Jeep Trails and Pack Trails leading to alpine features such as Lake Como, Little Bear Lake, and Zapata Falls. The map also delineates the county line between Alamosa Co and Costilla Co as it crosses the rugged eastern ridges.
