Mysterious and dangerous holes in Mt. Baldy, Indiana Dunes

IGS geologist and assistant director for research Todd Thompson is one of a team of researchers who recently returned to Mt. Baldy, a large sand dune in the Indiana Dunes National Lakeshore, to determine the cause of some mysterious holes. Last summer, a 6-year-old boy fell into a hole and barely survived being buried under 11 feet of sand for 3½ hours. The dune has been closed since the accident. The working theory is that old trees buried under the sand have disintegrated, which causes the sand to collapse. See a video and read more about the holes at the link below.
