The surface bedrock under the Miami area is called Miami oolite or Miami limestone This bedrock is covered by a thin layer of soil and is no more than 50 feet (15 m) thick Miami limestone formed as the result of the drastic changes in sea level associated with recent glacial periods or ice ages Beginning some 130,000 years ago the Sangamonian Stage raised sea levels to approximately 25 feet (8 m) above the current level All of southern Florida was covered by a shallow sea Several parallel lines of reef formed along the edge of the submerged Florida plateau stretching from the present Miami area to what is now the Dry Tortugas the area behind this reef line was in effect a large lagoon and the Miami limestone formed throughout the area from the deposition of oolites and the shells of bryozoans Starting about 100,000 years ago the Wisconsin glaciation began lowering sea levels exposing the floor of the lagoon by 15,000 years ago the sea level had dropped 300 to 350 feet (90 to 110 m) below the current level the sea level rose quickly after that stabilizing at the current level about 4,000 years ago leaving the mainland of South Florida just above sea level, 1850 159 -64.3% The new Park enjoyed instant popularity For a time county government honored the "separate but equal" status of Virginia Key Beach with its white counterpart Crandon Park on Key Biscayne the original temporary buildings were replaced by permanent construction a miniature railroad carried beachgoers around the park and a seaside merry-go-round whirled riders of all ages Still Crandon Park was over 800 acres (3.2 km2) with two miles (3 km) of beachfront and Virginia Key 82 acres (330,000 m2) with a half-mile of beach, A series of biennial reports from the U.S National Research Council have reviewed the progress of CERP the fourth report in the series released in 2012 found that little progress has been made in restoring the core of the remaining Everglades ecosystem; instead most project construction so far has occurred along its periphery the report noted that to reverse ongoing ecosystem declines it will be necessary to expedite restoration projects that target the central Everglades and to improve both the quality and quantity of the water in the ecosystem to better understand the potential implications of the current slow pace of progress the report assessed the current status of ten Everglades ecosystem attributes including phosphorus loads peat depth and populations of snail kites birds of prey that are endangered in South Florida Most attributes received grades ranging from C (degraded) to D (significantly degraded) but the snail kite received a grade of F (near irreversible damage) the report also assessed the future trajectory of each ecosystem attribute under three restoration scenarios: improved water quality improved hydrology and improvements to both water quality and hydrology which helped highlight the urgency of restoration actions to benefit a wide range of ecosystem attributes and demonstrate the cost of inaction Overall the report concluded that substantial near-term progress to address both water quality and hydrology in the central Everglades is needed to reverse ongoing degradation before it is too late.
