1911 Map of Grimes

About this map

The Sacramento River meanders sharply through the heart of this landscape, defining the boundary between Sutter and Colusa Counties during the early twentieth century. The settlement of Grimes serves as a primary riverfront hub, while the nearby Rancheria reflects the complex cultural history of the Sacramento Valley. This survey reveals a terrain defined by its complex hydrology, where numerous waterways like Corbiere Slough, Sycamore Slough, and Dry Slough drain the land toward the river. Low-lying depressions form distinctive water bodies such as Cecil Lake and Sills Lake. Along the riverbanks, features like Twentymile Bar and Gravel Pt indicate the shifting nature of the river channel, while the Montezuma Hills rise to the west. Infrastructure is represented by the Hannum Bridge, providing a critical crossing over the slough network that dominates the valley floor.
