Yet another large sinkhole swallowed up a healthy chunk of The Sunshine State on Monday. Measuring approximately 100 feet across, it opened up yesterday at the Summer Bay Resort close to Disney World, Florida, nearly taking one of the luxury vacation buildings with it while partially crumbling two others. (Fortunately, the 40 guests inside were able to get out in time and there were no injuries, although many â€“ wisely â€“ rushed out leaving everything behind.) Geologists are calling it a classic sinkhole, common in the Florida area due to the landsâ€™ predominant geologic rock formations of limestone, which are water-soluble and susceptible to whatâ€™s known as raveling, a vertical and/or lateral migration of sediments to deeper voids or cavities within the limestone. This shifting of that sediment causes the collapse, which creates a sinkhole â€“ and should remind travelers that â€œstand your groundâ€ has a double-barreled meaning down in God’s Waiting Room.
