What do wealth, power, death, and an elephant have in common? They comprise part of the colorful history of Boca Chita Key, where the Boca Chita Lighthouse is located. Although not a true lighthouse, it is the most popular structure on the small island. It was built by Mark Honeywell, the founder of Honeywell, Inc. and a previous owner of this once private island. Now owned by the U.S. National Parks Service this island in Biscayne Bay is a popular spot with boaters.
