It can strike suddenly after centuries of hiding, and will devour anything in its path. Sounds like a horror movie plot, but in reality there could be a sinkhole on your land. Some sinkholes have been correlated to land-use practices, especially from groundwater pumping, construction, and development. They can also form when natural water drainage patterns are changed and new water diversion systems are put in. If something looks suspicious on your land, the first thing to do is check out the neighborhood because sinkholes tend to be widespread. Then call your local NRCS office.
