Child Swallowed By Sinkhole Buried for 3 Hours Miracle Survival Story Parents Greatful. Faith and Greg Woessner, whose 6-year-old son, Nathan, survived being buried by a sand dune for close to four hours, talk about his recovery, saying "we are extremely thankful" for everyone who worked to save him. The parents of a 6-year-old boy who has made a remarkable recovery after being trapped beneath 11 feet of sand are thankful for the effort that resulted in him being pulled out alive. Nathan Woessner was enjoying a summer afternoon with his father and a friend on the shores of Lake Michigan on July 12 when he scampered up a sand dune and vanished in an instant. Woessner was buried under 11 feet of sand on Mount Baldy, a 126-foot sand dune at the Indiana Dunes National Lakeshore. The 6-year-old from Sterling, Ill., spent more than three hours trapped below ground, but somehow survived until rescue workers were able to pull him to safety. They rushed him to University of Chicago Medicine Comer Children's Hospital, and doctors expect him to make a full recovery. Nathan is currently doing "exceptionally well" and has been up and moving around, the boy's father, Greg Woessner, told Savannah Guthrie on TODAY Monday. "We're just very, very grateful for everything they did for Nathan,'' his mother, Faith Woessner, told Guthrie. "We can't express our gratitude enough for the rescuers, and the nursing staff and everyone that's helped bring Nathan back to us, and we're thankful to God for being there with us and bringing Nathan back to us."
