MICHIGAN CITY | Investigators have discovered another hole at the Mount Baldy dune similar to the hole that enveloped a 6-year-old Illinois boy in July.
The National Park Service and the Environmental Protection Agency on Monday began using sensing equipment at the Indiana Dunes National Lakeshore to look for anomalies in the sand dune.
Supervisory Park Ranger Bruce Rowe, who is the public information officer for the IDNL, announced Wednesday morning investigators found a hole, about 10 inches in diameter, in the surface of the dune. The hole resembles the size and shape of the hole described by the family of Nathan Woessner, the boy who was trapped under the sand for several hours.
Rowe said the hole appeared to be 5-feet deep but may have been deeper and the sand at the bottom was very loose. Investigators said the hole was not created by human activity and is believed to have formed as a natural phenomenon. Samples of the sand and debris within the hole have been collected and will be analyzed.

Rowe said more equipment was being taken to Mount Baldy on Wednesday to collect sand samples from various depths within the hole, if it still exists, and areas near the location of the hole.
The samples could provide the dates of the sand deposition under this area of loose sand, he said.
Among the testing conducted this week by the EPA was ground-penetrating radar, which investigators hope will create a three-dimensional model of the dune.
The Mount Baldy area of the Indiana Dunes National Lakeshore will remain closed to the public until further notice.
