A Duluth man was in critical but stable condition at Grady Memorial Hospital in Atlanta Tuesday after falling down a steep waterfall in the remote Glade Shoals area of North Hall.

Drake Hamilton, 19, suffered head injuries from the fall and was unconscious at the time he was flown to the hospital from Ga. 52 by a helicopter.

He was with five other people on the private property east of Clarks Bridge Road at the time of the accident.

The start of the waterfall is about 50 yards off the road and then “meanders down ... about 50 to 60 feet,” Hall County Fire Chief David Kimbrell said.

The rescue by Hall County Fire Services took about an hour and involved putting Hamilton in a basket and pulling him to safety through a pulley system.

John Vardeman, a spokesman for the Glades Farm property owners, has said the property owners are pressing charges against the teens who were on the property.

Col. Jeff Strickland, spokesman for the Hall County Sheriff’s Office, said the sheriff’s office is investigating the incident and that criminal trespass charges are possible against the six people.
