MICHIGAN CITY, Ind. -- Geologists beginning an in-depth study of why a then-6-year-old Illinois boy became buried in a popular sand dune in northwest Indiana last year have discovered another hole there.
Indiana Geological Survey Assistant Director Todd Thompson told the media Thursday the hole developed Wednesday while geologists were conducting tests on what caused Nathan Woessner to be buried alive in July 2013. He says it is the sixth hole that's been found.
Geologists from the survey, Indiana University and Indiana University Northwest arrived Monday at Mount Baldy to continue to study what is causing holes on Mount Baldy, a popular 126-foot high dune at the Indian Dunes National Lakeshore along Lake Michigan.
The dune has been closed for 13 months. Park spokesman Bruce Rowe says it will remain closed indefinitely.
