1963 Map of Shields Creek

About this map

Yankee Jim Ranch anchors the western edge of this landscape, a region defined by the complex drainage systems of the Warner Mountains. The terrain is a network of deep canyons and water sources, including the headwaters of Shields Creek and the Dry Creek Basin. As a 1963 survey updated with early 1980s data, the map illustrates the careful management of these high-altitude resources within the Modoc National Forest. Notable infrastructure like the Porter Reservoir with its recorded spillway elevation and the rugged Parker Creek Road highlight the human presence in this otherwise remote wilderness.
