Chileno Valley defines the northern reaches of this coastal landscape, where the Sonoma and Marin County line cuts through a series of steep ridges and pastoral drainages. The area is dominated by the intricate watershed of Walker Cr and its tributaries, including Chileno Cr and Arroyo Sausal. These waterways flow through named topography such as Frink Canyon and Verde Canyon, reflecting the complex physical geography of the California coast ranges.
