Check out this satellite imagery from Petaluma, California, a city of about 60,000 people in the northern bay area. The city completed construction of a new wastewater treatment plant, the Ellis Creek Water Recycling Facility, in 2009 and they included some polishing ponds which had a very interesting shape. Environmental artist Patricia Johnson worked with the city and their consultants to make this wetland park a unique piece of artwork. The shape is a reference to the harvest field mouse, an indigenous species in the area near the Petaluma River. You can see the actual treatment facility towards the top right of the image.
