An early description
In Charles Wilkes published "Narrative of the United States Exploring Expedition" documenting his five-year expedition (August 18, 1838 to June 10, 1842) which included several pages on Zonoma:
On the opposite side of the bay of San Pablo, or to the west, are some of the finest tracts of country in California. One of these is called the Valley of Nappa, another that of Zonoma, and a third San Rafael. In Zonoma is situated the town of the same name, the residence of General Vallejo, and the mission of San Rafael. The fertile country extends across to Ross and Bodega, two Russian settlements which have been ceded to Captain Suter. Zonoma is the seat of government, and is situated in an extensive plain, with some high hills for its southern boundary. The plain is covered with fine oaks, and there is a never-failing stream of water passing through it. There is besides an inlet from the bay, which allows a boat navigation to it of about twelve miles.
