An 8-year-old girl remained hospitalized Sunday after falling 10 to 15 feet from a zipline at Camp Letts, according to the Anne Arundel County Fire Department.

Emergency personnel were called to the camp in the Edgewater area south of Annapolis around 2:39 p.m.

The child was airlifted to the Johns Hopkins Children’s Center in Baltimore, where she was listed in serious condition.

A fire department spokesperson said the child remained hospitalized Sunday but did not know the child’s condition. A hospital spokesperson said they were unable to provide an update without the patient’s name.

Camp Letts, founded in 1906, is run by the YMCA of Metropolitan Washington. A spokesperson said a private event was held by an outside organization that had been using the camp, and an outside vendor set up the zipline.

“The YMCA of Metropolitan Washington has been informed that an attendee of a private event held by an outside organization was injured while on the YMCA Camp Letts Retreat Center property,” a spokesperson said in a statement. “It was reported to the YMCA that a juvenile guest fell while using an outside vendor’s zipline set up specifically for the event. The Y sends prayers for the individual’s full recovery.”
