Mystery Holes Form At Indiana Dunes

Officials have shut down a popular public sand dune in Indiana where mysterious holes are appearing — one of which swallowed up a boy for 3 hours last summer. 2 more holes have opened up since then and other depressions have been sighted prompting the shutdown. But no one knows why it’s happening; the holes, which measure about a foot in diameter, exist for nor more than 24 hours, at which point they collapse and are refilled with neighboring sand. Geologist Erin Argyilan says, “We’re seeing what appears to be a new geological phenomenon.”
