Mount Baldy Closed This Summer - Large Sink Holes in Dunes

[Andie]

No explanation as yet. One boy fell into one and luckily was rescued.

Certainly a lot of sink holes being reported all over the country.

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 Mt. Baldy in Indiana Dunes National Lakeshore. Additional research will be conducted this summer and may last into the fall. To ensure the public’s safety, Mount Baldy, its parking lot, trail, and beach in front of the dune will remain closed to all vehicular and pedestrian access while the investigation continues.

 

Scientists are now preparing for a more comprehensive investigation of the dune this summer. This study will include mapping of openings, depressions, and anomalous features, the use of multispectral Ground-Penetrating Radar (GPR) and coring to develop a better understanding of the overall internal architecture of the dune, and detailed GPR and coring of some of the anomalies identified in the EPA report.
