Friends heard the girl call out and then heard sounds of her falling from the ledge. The drop-off was between 80 and 100 feet, Warchock told The Associated Press.
O’Brien, who lives in nearby Gwinn, was found lying amid large boulders and rock debris along the lakeshore.
Warchock told The Mining Journal she suffered rib, arm and spleen injuries. She underwent surgery and is recovering at Marquette General Hospital, he said.
“I think she’s doing well considering,” he told the AP.
Marquette firefighters lowered ropes and went down the cliff face to reach O’Brien. They talked with her while other helpers were on the way.
“They got down to her fairly quickly,” Warchock said.
After a U.S. Coast Guard boat arrived, crews put O’Brien on a stretcher and moved her to the boat. She was rushed to an ambulance at the Upper Harbor marina.
