Researchers Use Ground-Penetrating Radar to Understand Holes in Mount Baldy Dune
Illinois researchers are still searching for the reason for the many sudden holes forming in the dunes at Mount Baldy.
The area of the Indiana Dunes National Lakeshore was shut down for public visitation on when six-year-old Nathan Woessner was swallowed by a large hole in the dune. Though he recovered from the accident, he was buried in 11 feet of sand for 3½ hours before rescuers were able to get him out.
The incident sparked an ongoing research effort to discover the reason that holes are suddenly forming in the 126-foot-tall dune. Three of the effort's primary researchers met in the cordoned-off area on Thursday to discuss recent findings.
A new wave of research that began Monday includes geological probes and ground-penetrating radar to build on radar data that the Environmen...
