1909 Map of Cosumnes

About this map

Cosumnes River corridors and rural schoolhouses define this 1907 survey of eastern Sacramento County. The landscape is marked by the winding path of Deer Creek and the southern reach of Laguna, where the terrain transitions from river bottoms to upland plains. Slough House and the settlement of Cosumne stand as primary hubs of activity along the historic Jackson Road, which served as a vital freight and travel artery for the region. The map reveals a decentralized educational network of the early twentieth century, with family-named landmarks such as Rhoads School, Wilson School, and Lee School positioned to serve the surrounding ranching and agricultural community. These small, scattered school sites provide significant genealogical clues, anchoring the rural population to specific parcels before the era of district consolidation.
