1912 Map of Keefers

About this map

Arroyo Chico defines the southern extent of this 1910 survey, where the drainages of the Sierra Nevada foothills meet the upper Sacramento Valley floor. This preliminary edition, surveyed by R.B. Marshall and his team, provides a detailed look at the hydrology of the area before extensive modern development. The landscape is characterized by the branching paths of Mud Creek, Sycamore Creek, and Chico Creek, which have carved distinct features into the terrain such as Sheep Hollow and Sycamore Hollow. The map captures a transitional geography where seasonal watercourses like Sandy Gulch emerge from the uplands, illustrating the natural drainage patterns that would later influence the agricultural and residential footprint of this portion of Butte County.
