1918 Map of Princeton

Extensive land grants are represented by the Larkin's Children Rancho Boundary Line, which spans a significant portion of the interior. To the north and west, the terrain is marked by seasonal drainages like Willow Creek and Shepards Slough, while smaller family-named landmarks such as Harrison and Ferris offer valuable data points for genealogists tracking early twentieth-century inhabitants. The map also detail specific river features like Packer Island and the meandering Rasor Slough, capturing the valley's complex hydrology before extensive modern levee systems altered the flow.
