1972 Map of Loggerhead Key

About this map

Loggerhead Key and its surrounding tropical waters are documented here in the early 1970s through a combination of aerial orthophotography and planetable surveys. The map provides a detailed view of the submerged reefs and shallow flats of the lower Florida Keys, transitioning from the sheltered Newfound Harbor Keys and Big Munson Island out into the deeper Hawk Channel. A critical maritime infrastructure is visible along the northern edge, where the Intracoastal Waterway cuts through the shallows, supported by a Light for nighttime navigation. Further south, the coral structure of Looe Key stands as a prominent landmark before the seafloor drops away into the vast Straits of Florida. This survey serves as a precise record of the shoreline and reef configurations prior to later environmental shifts and modern development.
