Using bows and arrows, spears or snares, Patwins stalked the abundant turtles, deer, tule elk, antelope and the occasional bear, mountain lion or wild cat that came down from the foothills and Coast Range.

Using bow and arrow or nets they hunted ducks, geese and swans as they came into the tule marshlands during migrations.

Between 1829 and 1846, hunters and fur trappers from Santa Fe, New Mexico and from Hudson's Bay Company in Fort Vancouver sometimes traded with Patwin resulting in heavy losses of life for the trappers and hunters and for Patwin.

The coming of the Yolo County Consolidated Water Company's system in 1903 to Black's added much to the importance of the place and stimulated business.

[3] Prairie Post office was opened on March 19, 1857, at Weyand's Corner where a rural hotel, general store and stage stop were run at the ranch of Theodore Weyand, located at County Road 97 and County Road 13.

The hotel burned and Zamora post office moved to the IOOF building where Carey L Croll became postmistress in 1924.

In 1957, Zamora Post Office returned to the IOOF building with Ruth Anderson as postmistress.
