The Petaluma River and its intricate McNear Channel define the eastern urban edge of Petaluma, where the city transitions into the fertile dairy lands and valleys of the Sonoma-Marin border. This 2015 record documents the convergence of historical cemetery sites such as Cypress Hill Memorial Park, Bnai Israel Cemetery, and Petaluma Calvary Cemetery north of the downtown core. The landscape quickly shifts from the gridded streets of East Petaluma to the rolling terrain of the Chileno Valley and Hicks Valley, areas defined by long-standing agricultural tracts and rural routes like Burns Dairy Rd and Spring Hill Rd.
