Correct me if I'm wrong, but the cover picture is of a sinkhole in Guatemala that opened in April of 2007 and was not the result of the workings of a karst system, but rather the result of the workings of piping caused by faulty drainage systems installed in poorly consolidated volcanic ash substrate. If this is correct I am led to conclude that the sinkhole is the result of human engineering error, and not the result of a karst system. I recall a past CaveTex posting citing a study with this conclusion.
I know you shouldn't judge a book by it's cover, but really? Justin
