1918 Map of Logan Creek

About this map

The drainage basins of the Sacramento Valley foothills emerge in this 1904 survey, documenting the sharp contrast between the rugged terrain and the flat valley floor. Logan Creek flows eastward out of the hills, joined by the North Fork Logan Creek as it moves toward the agricultural lands of the valley. Further south, Hunters Creek carves through the undulating topography, illustrating the natural watercourses that defined early land boundaries and ranching potential in this region. The map also delineates the jurisdictional divide at the Glenn Co Colusa Co Boundary line, providing a clear view of the county boundaries at the start of the 20th century. Large sections of the western hills remain marked as an Unsurveyed Area, reflecting the era's frontier mapping priorities where the steep interior ridges were yet to be fully documented by the Geological Survey.
