2015 Map of Wildwood School

About this map

The Wildwood School and the settlement of Harrington anchor this section of the northern Sacramento Valley along the boundary of Colusa and Yolo Counties. The landscape is defined by the transition from the flat agricultural plains of the Central Valley into the dissected topography of the Dunnigan Hills. The massive Tehama Colusa Canal bisects the terrain, providing a critical industrial water corridor that cuts across natural drainages like Petroleum Creek and Buckeye Creek. This 2015 survey details the geometric grid of county roads, such as Harrington Ave and Wildwood Rd, which contrast with the winding courses of Salt Creek and Mushoak Cr. The infrastructure of Old Highway 99W runs parallel to the modern interstate, tracing the historical transit spine of this rural region.
