The rainfall in California is rather phenomenal, and depending greatly upon latitude 

 and topography. The average difference of annual rainfall in the State, extending from 

 northwest to southeast, is a little over two inches for every degree, being thirty-four 

 inches at Crescent City, and ten inches at San Diego. It is said to increase about one 

 inch for every hundred feet in elevation in ascending the Sierra Nevada.
