Last Ones Left in Treece, Kan., a Toxic Town - NYTimes.com: One problem with Treece, Kan., is that the ground keeps caving in. It has happened more than a hundred times over the last century. On most occasions, the subsidences — that’s what the scientists call them — are small, like when a sofa-size crater opened up on 10th Street last year. Other times, they are much worse. In 1966, a 300-foot-wide, 200-foot-deep abyss swallowed up the road out on the edge of town. Somehow no one died.
