Sinkholes are natural phenomena that happen, among other places, on top of the Floridian Aquifer, which is where we live. It is gigantic and runs through limestone tunnels and gravel underneath us. During a drought or because of drawdown or because of natural dissolution of the lime, little bits subside. In an area with quite a bit of clay and sand over the underlying limestone, which is big parts of Florida, this subsidence may not show on the surface. In other big parts of Florida, including where we live and Ocala and Silver Springs and all that, there is mostly some sand over the limestone layers and two or three aquifers, so we are more likely to notice a subsidence as a sinkhole. A big one might ruin a couple houses, but it won’t swallow a village. When the water in the pond disappeared, it ran into cracks in the rocks and gradually into the top aquifer, which we don’t use for drinking, usually. Under that is a layer of clay that is hard for water to penetrate. Under that is the Floridian Aquifer, which is mammoth.
