About this map

Cache Creek winds through the heart of this landscape, carving a deep path through the canyon lands of the northern California interior. In the late 20th century, this area remained largely defined by its natural drainage systems and dramatic topography, with Wilson Valley and Morgan Valley providing the few relatively level stretches of ground amidst the ridges. The map reveals a network of water sources such as Dunfield Spring and Bear Spring that were vital for any historical activity in these hills.

Remote trails and primitive routes like the Pack Trail suggest a region used for rugged access rather than intensive development. Prominent landmarks such as The Peninsula and Grizzly Peak serve as navigational anchors across the county lines of Lake, Colusa, and Yolo. The naming of local features like Kennedy Flats and Dunfield Flats indicates a history of localized land use, likely tied to early ranching or homesteading efforts in these isolated pockets of the Coast Ranges.
