2022 Map of Cordelia

About this map

Elkhorn Peak and the southern reaches of the Howell Mountains dominate this view of the Napa and Solano County line. The landscape transitions from the upland ridges of Sulphur Springs Mtn and Sky Valley into the expanding residential and industrial corridors of Vallejo, American Canyon, and Fairfield. The transportation network is a central theme, with Jameson Canyon Rd cutting through the hills toward Cordelia Junction, a major crossroads since the early days of regional transit. Insights into the area's development are found in the planned neighborhood footprints of Chabot Terrace and Harry Floyd Terrace, as well as the preservation of open space around Terminal Reservoir. Small drainages like American Canyon Cr and Fagan Cr etch the terrain, while roads like St Johns Mine Rd hint at the historical extractive industries that once operated in these foothills.
