1968 Map of Julian Rocks

About this map

Julian Rocks rises as a prominent landmark in this Glenn County landscape, where the foothills meet the upper reaches of water management infrastructure. The northeastern corner is dominated by the Black Butte Lake Spillway, an area surveyed with underwater contours to capture the topography of the reservoir's edge. This 1960s environment is defined by a sparse network of ranching outposts and remote homesteads, including the Stone Valley Ranch, Wilson Place, and Lyons. A web of Jeep Trails provides the only overland access through the complex drainage systems of Stony Creek and its many tributaries, such as South Fork Walker Creek and French Creek. The map documents a rugged interior of unnamed ridges divided by seasonal watercourses like Sheep Corral Creek and White Cabin Creek, reflecting the isolation and traditional land use of the northern Sacramento Valley foothills before later modernization.
