Explains the formation of Florida's sinkholes and discusses Florida's sinkhole policies, mapping, and detection.

Text and photographs explore sinkholes, a natural phenomenon caused by the interaction between rock and water.

Fifty years ago, no one could explain mountains. Arguments about their origin were spirited, to say the least. Progressive scientists were ridiculed for their ideas. Most geologists thought the Earth was shrinking. Contracting like a hot ball of iron, shrinking and exposing ridges that became mountains. Others were quite sure the planet was expanding. Growth widened sea basins and raised mountains. There was yet another idea, the theory that the world's crust was broken into big plates that jostled around, drifting until they collided and jarred mountains into existence. That idea was invariably dismissed as pseudo-science. Or "utter damned rot" as one prominent scientist said. But the doubtful theory of plate tectonics prevailed. Mountains, earthquakes, ancient ice ages, even veins of gold and fields of oil are now seen as the offspring of moving tectonic plates. Just half a century ago, most geologists sternly rejected the idea of drifting continents. But a few intrepid champions of plate tectonics dared to differ. The Mountain Mystery tells their story.

This book discusses the geology, hydrogeology, and water quality/geochemistry of karst systems in geologically young terrain, using the state of Florida as an example. Also discussed are sinkhole-development models; sinkhole risk; eogenetic karst features developed in rocks as young as 125,000 years and as old as 65 million years; and karst landscapes of Florida, including regional geology and geomorphology with important examples of karst features, such as springs, sinkholes, caves, and other karst landforms. The eogenetic karst of Florida is largely covered and this book extensively discusses the interactions of karst processes with sand- and clay-rich cover materials.

The Villages® retirement community in Central Florida is home to 700+ holes of golf, 200+ pickleball courts, 100 recreation centers, 100+ swimming pools, 3,000+ resident clubs and organizations, 100+ restaurants, a wide range of shops, grocery stores, and medical offices, free live entertainment nightly, and to top it off, nearly everything is golf cart accessible. With all of that in mind, it's no wonder why 130,000 retirees call it home.Yes, it's an incredible place, but it's not for everyone. Thousands of people buy and move here every year, but thousands more take a close look and decide it's not for them. This book was written to help you decide if it's the right place for you.
