The oldest Amerindian culture was the Onamonalonton center in California, but this had long since vanished by 35,000 B. C. [1]
Onamonalonton lived to be ninety-six years of age and maintained his headquarters among the great redwood trees of California. Many of his later descendants have come down to modern times among the Blackfoot Indians. [2]
The immense arctic North American inland sea found an outlet to the Pacific Ocean through northern California. [3] Rich fossil beds are situated along the coast of California. [4]
190,000,000 years ago witnessed a westward extension of the North American Carboniferous sea over the present Rocky Mountain region, with an outlet to the Pacific Ocean through northern California. [5] 180,000,000 years ago brought the close of the Carboniferous period. Volcanoes were active in Alaska and California. [6] The Pacific coast, usually above water during the continental submergences, went down excepting the southern part of California. [7] Great volcanic actions occurred south of the Alps and along the line of the present California coast-range mountains. [8]
25,000,000 years ago there was a slight land submergence following the long epoch of land elevation. The great four-mile vertical fault in the California region dates from this time. [9]
