Environmental Protection Agency and National Park Service investigators say they have found a new hole in the state’s tallest sand dune where a 6-year-old boy was trapped under 11 feet of sand last month.
The hole in Mt. Baldy at the Indiana Dunes National Lakeshore is about 10-inches in diameter and at least five feet deep.
Testing and analysis of results will take weeks, and the entire Mt. Baldy area will remain closed to the public until further notice.
“The fact that we do not know what caused the original hole, and that a new hole has spontaneously appeared, reinforces our concern that Mt. Baldy is not safe for visitors at this time,” park superintendent Constantine Dillon said in a statement.
ABC News reported in July that 6-year-old Nathan Woessner was buried alive for more than three hours before rescue crews pulled him out.
Woesneer is expected to make a full recovery.
