Pickles Reef, Coral reef in Florida Keys National Marine Sanctuary, United States.
Pickles Reef is a coral formation in the Florida Keys National Marine Sanctuary located southeast of Key Largo. It features extensive brain coral and branching Acropora palmata structures alongside populations of spotted trunkfish, stoplight parrotfish, and spotted moray eels.
The reef developed within a period of heavy maritime activity and still contains wreckage from a two-masted iron vessel and concrete structures dating from 1890 to 1923. These remnants provide evidence of the region's maritime past.
The reef functions as an educational center where researchers study marine ecosystems and document the effects of climate change on coral communities.
Navigation buoys mark the reef location for snorkelers and divers to navigate the area safely. The underwater topography accommodates visitors of varying skill levels.
The concrete structures scattered across this location were initially mistaken for Civil War cargo but analysis proved them to be Portland cement from a later era. This confusion highlights how challenging it can be to correctly interpret marine archaeological finds.
