Mount Baldy at Indiana Dunes to remain closed
Mount Baldy at the Indiana Dunes Park will remain closed this summer because of mystery holes, officials announced Thursday.
“Despite the use of ground penetrating radar, and data gathering at two additional holes that have appeared since last July, scientists still don’t know the cause of the holes at Mount Baldy in Indiana Dunes National Lakeshore,” the National Park Service said in a statement. “Additional research will be conducted this summer and may last into the fall.”
The parking lot, trail and beach in front of Mount Baldy will also be closed.
Mount Baldy has been closed since last summer when 6-year-old Nathan Woessner, fell into one of the holes and it collapsed around him. He survived four hours under the sand because he was trapped in an air pocket.
After the rescue, officials began investigating what caused the holes. They have so far been unable to determine a cause.
According to the National Park Service, “two additional holes and a number of depressions have been found during the ongoing investigation and continued monitoring of the dune. Scientists report that the holes are short-lived, remaining open for less than 24 hours before collapsing and filling in naturally with surrounding sand.”
A more comprehensive investigation will begin this summer.
