Miami Limestone (formerly Miami Oolite, orange on map) in relation to other formations in South Florida. The Miami Limestone, originally called Miami Oolite, is a geologic formation of limestone in southeastern Florida. Miami Limestone forms the Atlantic Coastal Ridge in southeastern Florida, near the coast in Palm Beach, Broward and Miami Dade ...
These forests form on limestone outcrops with very thin soil; [2] the higher elevation separating them from other habitats such as coastal marshes and marl prairies. [3] On mainland Florida, rocklands exist primarily on the Miami Rock Ridge, which extends from the Miami River south to Everglades National Park.
The Miami Rock Ridge is an oolitic, continuous outcrop of limestone, part of the Miami Formation, which formerly encompassed a large extent of southernmost South Florida; as part of an ecosystem it formed portions of the Everglades.
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.
Miami experienced a second real estate boom that earned a developer in Coral Gables $150 million. Undeveloped land north of Miami sold for $30,600 an acre. [124] In 1925, Miami newspapers published editions weighing over 7 pounds (3.2 kg), most of it in real estate advertising. [125] Waterfront property was the most highly valued.
A map of the aquifer. The Biscayne Aquifer, named after Biscayne Bay, is a surficial aquifer. It is a shallow layer of highly permeable limestone under a portion of South Florida. The area it underlies includes Broward County, Miami-Dade County, Monroe County, and Palm Beach County, a total of about 4,000 square miles (10,000 km 2). [1]
Florida City is situated mostly atop a limestone ridge called the Miami Rock Ridge [7] that extends south from present day North Miami Beach [8] to a location in Everglades National Park. [9] The ridge, consisting of Miami limestone, [10] serves as the higher ground within the community. The ridge extended from northeast to southwest across the ...
Eventually, the site was acquired by Miami-Dade County. It now is part of the Charles Deering Estate Park. [1] [2] [3] The Cutler Fossil Site is located in a sinkhole on the Miami Rock Ridge, a karstitic limestone formation running near the coast in Miami-Dade County. The ridge at the site is approximately 5 metres (16 ft) above the current sea ...
