Opa-locka’s center stands about 10 ft above sea level. Within three miles the land runs from 0 ft to 30 ft, a difference of 30 ft: nearly flat ground.
Under the town center the state geologic map shows Miami Limestone (limestone, sandstone), from the Pleistocene, less than 2.6 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, sandstone. Age: Pleistocene, less than 2.6 million years old. About 19 mi of the line.
