The boy, who nearly lost his life when he was buried alive at the Indiana Dunes, is back in school.
Nathan Woessner fell into a hole where nearly 11 feet of sand collapsed on top of him.
Firefighters worked for hours to save his life, and after making a full recovery, Nathan is in first grade playing alongside his classmates.
Doctors were worried about grains of sand left in Nathan’s lungs, and they feared the boy would have breathing problems.
But so far, Nathan has not experienced any discomfort.
In the meantime, investigators continue testing samples at the Indiana Dunes.
Last week, a second hole was discovered at Mount Baldy.
Its 10-inches wide and 5-feet deep.
It was found 100 yards from the hole that Woessner fell in last month.
