Destroyed 1840-1841 Winter Flood
In 1834, Mariano G. Vallejo's brother-in-law, John B. R. Cooper, constructed California's first known power-operated commercial sawmill. In addition to sawing redwood lumber, the mill and surrounding settlement served as a barrier to Russian encroachment from the west. Located 1/3 mile east on Mark West Creek, the water-powered mill was destroyed by flood in the winter of 1840-41.
