About this map

The hills and canyons of southeastern Napa and Solano Counties are mapped here during a period of transition, following the 1951 survey with 1968 updates. Residential developments like Chabot Terrace, Flosden Acres, and Harry Floyd Terrace expand toward the County Fairgrounds on the outskirts of Vallejo, while the industrial and agricultural character of the land persists elsewhere. The Southern Pacific railroad remains a primary transit corridor, winding through Jameson Canyon past Creston toward the junction at Cordelia.

Evidence of the area's extraction economy and community life is found in the mercury-producing St John Mine near Sky Valley and local landmarks like the Drive-in Theater and American Canyon School. The landscape is defined by its drainages, including American Canyon Creek and Sulphur Springs Creek, which feed into Lake Chabot. The 1960s revisions reveal urban expansion as purple-tinted areas, documenting the post-war growth of this Northern California corridor.
