Rancho Suscol

The Rancho Nacional Suscol was a national ranch under his control, heavily stocked with cattle and horses.

Aiding Vallejo in various battles in exchange for cattle and other goods, Patwin populated this land living along the banks of Suscol Creek.

Vallejo also received a confirming document (later considered to be a forgery by the US Supreme Court) signed by Pio Pico in 1845.

With the cession of California to the United States following the Mexican–American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored.

Frisbie sold portions of the tract to San Francisco investors who were primarily interested in speculating on the growth of Benicia, Vallejo and the Mare Island Naval Shipyard.
