Portrayed is the California side of Christo's Umbrella Project. The yellow umbrellas took over an inland valley in California and blue umbrellas took over an inland valley in Japan. 

 Christo Javacheff is noted for his environmental sculptures throughout the world. His pieces are known for being experimental with their vibrant colors and large scale operations. He worked alongside his wife Jeanne-Claude.
