Bright afternoon sunlight dances and reflects off the tiny rivers of Los Angeles, creating swirls and whirls of reflected light.                    

Disney Concert Hall, night.                     Downtown Los Angeles skyscrapers: under bright sunlight.                    

Trees shade the tiny streams high up in the San Gabriel Mountains. But between the brown branches and green leaves the hot summer sun shins through. The sharp sunlight reflects in swirls and patters on top of the flowing water.
