About this map

Sulphur Springs Mountain and Sky Valley dominate the central landscape of this mid-century topographic survey, where the rugged terrain of the American Canyon meets the expanding residential developments of Vallejo. The map documents a period of rapid post-war growth, particularly evident in the planned streets of Chabot Terrace and Harry Floyd Terrace near Lake Chabot. This urban expansion is balanced by persistent industrial and agricultural activity, from the St John Mine and various quarries to the numerous windmills dotting the hillsides.

Transportation corridors play a defining role, with the Southern Pacific railroad and a significant Pipe Line bisecting the quadrangle. To the east, the historic junction at Cordelia serves as a gateway toward Suisun, while the southwestern corner highlights institutional landmarks like the Permanente Foundation Hospital and the County Fairgrounds. The mapping of small settlements like Creston and Napa Junction provides a precise record of the Solano and Napa County borderlands before modern suburban infill.
