Chileno Valley forms a prominent agricultural corridor through the Marin and Sonoma County borderlands, anchored by the meandering Chileno Cr. This 2021 survey illustrates the contemporary landscape where the coastal hills meet protected inland territories. The southern portion of the map is dominated by the sprawling Golden Gate National Recreation Area, protecting the drainages of Millerton Gulch and the rugged heights of Bolinas Ridge. To the east, the Soulajule Reservoir acts as a significant hydrologic feature, capturing the waters of Arroyo Sausal. This map details a high-relief terrain of canyons and peaks, such as Frink Canyon and the distinctive Three Peaks, while tracing rural routes like Tomales Petaluma Rd and Chileno Valley Rd that have long connected these northern California ranching communities.
