Miami Limestone forms the Atlantic Coastal Ridge in southeastern Florida, near the coast in Palm Beach, Broward and Miami Dade counties. It also lies under the eastern (Miami-Dade County) part of the Everglades, Florida Bay, and the lower Florida Keys from Big Pine Key to the Marquesas Keys. [1] Mitchell-Tapping also states that a component of ...
The limestone that eroded from the reef formed oolites in the shallow sea behind the reef, and together with the skeletal remains of bryozoans, formed the Miami Limestone that is the current surface bedrock of the lower Florida peninsula and the lower keys from Big Pine Key to Key West.
The pine rocklands in Miami-Dade County and Everglades National Park are found on limestone substrates along the Miami Rock Ridge, an exposed oolitic limestone matrix 2–7 meters above sea level that extends from northern Miami to the southern Everglades with disjunct sections in the Lower Keys. [4] This limestone is extremely sharp, porous ...
The position of the Miami Rock Ridge largely corresponds with that of Pliocene reef tracts which extended from Palm Beach County to southern Miami-Dade County. [12] The oölitic (upper) facies of the Miami limestone caps the Miami Rock Ridge. It is up to 35 feet (11 m) thick along the ridge summit, but extends only part-way under the Everglades.
The globally imperiled pine rockland community, which also encompassed the Florida Keys and The Bahamas, supported numerous endemic plant species; 20 percent occur nowhere else in the world. [7] The communities of the Miami Rock Ridge are maintained by wildfires, including natural fires caused by lightning strikes; this affects the vegetation ...
The Key Largo Limestone are reefs up to 200 ft (61 m) thick, parallel to the shelf edge, consisting of hermatypic corals and calcarenites. The Miami Limestone is less than 49 ft (15 m) thick, and in general is found behind the Key Largo Limestone reef, but overlies it in the western extent of the keys.

[1] Extending from just south of Key Biscayne southward to just north of Key Largo, the park includes Soldier Key, the Ragged Keys, Sands Key, Elliott Key, Totten Key and Old Rhodes Key, as well as smaller islands that form the northernmost ...
