Often a depression is not verified by a licensed professional geologist or engineer to be a true sinkhole, and the cause of subsidence is not known. Above the rockhead, bed rock may be overlain with saprolite. The survey refers to the limestone as part of the Biscayne aquifer, and it specifies the limestone as "Miami Limestone." However, numerous subsidence features may also occur in fields and forests, many of which go unseen or are seen and are unreported. The upper boundary of bed rock is called its rockhead. How do I find which of Floridas statutes involve sinkholes? Southeast Florida, south of Palm Beach County, is one of those places in Florida where the sand cap, when present, can be shallow.

FL The rocks underlying Big Cypress Swamp are among the oldest in south Florida and are composed of silt, sand, and carbonate minerals. It is possible, in some cases, to perform geological tests on a piece of property and assess the potential for sinkhole development. Trees Drill into Deep Bedrock for Water Surprisingly Often It has the reputation of being made of sand, but that is not always the case. (such as sinkholes, springs, and caves.) Freshwater runoff and tidal fluxes cause the salinity to vary dramatically.
