2022 Map of Newville

About this map

Newville sits at the eastern edge of the interior Coast Range where the foothills meet the Central Valley. This area is characterized by a series of prominent northwest-trending geological structures, including Rocky Ridge, Digger Ridge, and Heifer Ridge. The transition from the rugged highlands of the Mendocino National Forest to the flatlands of the Sacramento Valley is marked by numerous watercourses such as Thomes Cr and Salt Cr that drain toward the valley floor. Transportation across this rural landscape relies on historic routes like Round Valley Rd and Newville Rd, which follow the natural contours of the terrain. The map also records the boundary between Tehama and Glenn counties, illustrating how political lines were drawn through this topographically complex region of Northern California.
