Out of This World Aerial Photographs of Purple Salt Ponds in San Francisco
The colorful pond you see in the above image is not the work of clever post–production; nor is it the result of an accidental leak of hazardous material. In fact, it's 100% natural. What you’re seeing are millions of colorful microorganisms that live and breed in the vibrant salt ponds of San Francisco.
The above image and its accompanying series, titled San Francisco Bay - Purple, was captured by photographer Julieanne Kost as she flew over the ponds, located south of San Francisco.
