What's the meaning behind the Miami Waterkeeper logo?

The circle in our logo is the outline of the Miami Circle – a Tequesta archaeological site situated at the mouth of the Miami River and Biscayne Bay. The site is a perfect circle measuring 38-feet across with 24 holes or basins cut into limestone, and containing shell tools, dolphin skulls, turtle shells, and shark teeth. The site was discovered in 1998, and is thought to be between 1700-2000 years old, indicating that the Circle represents one of the first-known interactions of humans and the water in the Miami area. The Miami Circle holds profound meaning for Miami Waterkeeper, as we focus on protecting and respecting wildlife, water, and all human inhabitants of South Florida. The animals found inside our logo are native to Biscayne Bay and the surrounding waters, including some listed in the Endangered Species Act. It is also a reminder that our jurisdiction covers the ancestral and traditional lands of the Seminole, Miccosukee, and Tequesta people.
