INDIANA (www.incnow.tv) -- Investigators are trying to determine what caused the sink hole at the Indiana Dunes National Lakeshore where a 6-year-old boy was swallowed up.

Nathon Woessner, 6, has been upgraded to serious condition after being trapped 11-feet underground. Mount Baldy has been closed indefinitely as the National Park Service works to make sure no one else gets hurt.

Parks spokesperson, Bruce Rowe, says they’re working to gather more information on how a possible hole was created by a decomposed tree, leaving the sinkhole where Woessner was rescued from Friday.

Park Rangers are keeping a close eye on the locked grounds. Along the beach you can still make out tire-tracks from the rescue. Officials believe Mt. Baldy is the only area that has this potential danger and is encouraging people to feel safe to visit the dunes.
