To develop our novel micro-meteorological instruments, we used a large cow-pasture east of Pasadena, which gently sloped up toward the San Gabriel mountains. We had a favorite demonstration of katabatic wind. We had a pole with eight wind vanes spaced about every half meter apart. In the afternoon, the sea breeze caused all the wind vanes to point toward the Pacific Ocean. As sunset approached, first the lowest wind vane on our pole turned and pointed toward the mountain as a shallow current of cold air flowed downhill. Somewhat later the second vane turned, then the third, fourth, fifth, sixth, seventh, and finally the eighth turned as the katabatic wind built up to be a deep gentle flow of cold air. Before sunset, we could almost tell the time of day by how many wind vanes pointed uphill. 

This paper is a summary of our findings from a four-year study of the chemical composition of fog and cloud water in California. Fog water was sampled at a number of sites with a rotating arm collector, which was developed in our laboratory and collects representative samples. Field investigations in the Los Angeles basin, the San Gabriel Mountains, and the San Joaquin Valley revealed very high ionic... 

The coastal ranges are not distinguished, despite their considerable altitude. The San Gabriel and San Bernadino Mountains, and even the San Gabriel Little Mountain are immediately recognized something that the small differences in relief cannot explain.
