*********************
The cache is NOT at the posted coordinates.

You will need to choose the correct lighthouse to get the correct coordinates.


This lighthouse is located midway between Fort Lauderdale and Boca Raton, in Hillsboro Beach, Florida. The light marks the northern limit of the Florida Reef, an underwater coral formation on the lower east coast of the state.

In 1901, the United States Lighthouse Establishment persuaded Congress to authorize the construction of a lighthouse in the dark area between Jupiter Inlet Light and Fowey Rocks Light. In the second half of the 20th century, this inlet became an increasingly busy waterway.

The octagonal iron pyramidal tower was built at Russel Wheel & Foundry Co in Detroit, Michigan, moved to the Hillsboro Inlet Light Station in 1906, and lit on March 7, 1907. Its second-order bivalve Fresnel lens emits a light measuring 5.5 megacandelas and is placed 136 feet (41 m) above sea level. Automated in 1974, the light acts both as a coastal navigational aide and as a support to local water traffic.

The light was relit in 2000; in 2003, the lighthouse was honored with a 37¢ U.S. postage stamp.
