1986 Map of Chicken Hawk Hill

About this map

The Sacramento River carves through the eastern edge of this landscape, marking a vital corridor where the settlement of Gibson sits alongside State Hwy 13. This mid-1980s survey documents a region defined by the intersection of the Trinity National Forest and Shasta National Forest, where the complex drainage systems of Mears Creek and Boulder Creek feed into the river valley. Higher elevations are marked by distinctive alpine features like Twin Lakes and Tamarack Lake near Mount Eddy, while lower slopes reveal traces of smaller-scale extraction and natural springs. The presence of Shiloah Mineral Springs and numerous Prospect labels suggests a history of both recreational interest and resource exploration in these steep California mountainsides, documented here just as modern environmental management was becoming established.
