The iconic lighthouse on Boca Chita Key in Biscayne National Park, Florida. More ornamental than functional, it sits right on the harbor entrance and provides an easy point for visual navigation to the island. Do you know the difference between a "key" and an "island"? All keys are islands but not all islands are keys. Hint: it has to do with how they are formed
