According to the Anne Arundel County Fire Department, an 8-year-old girl was hospitalized Sunday after falling 10 to 15 feet from a zip line at Camp Letts.

At around 2:39 p.m., rescue crews were called to the camp in the Edgewater area south of Annapolis.

The child was flown by helicopter to Johns Hopkins Children’s Center in Baltimore, where her condition was classified as serious.

A fire department spokesman said the child was still in the hospital on Sunday, but his condition was unknown. A hospital spokesman said they could not provide any updated information without the patient’s name.

Camp Letts was founded in 1906 and is operated by the YMCA of Metropolitan Washington. A spokesman said a private event was held by an outside organization that had used the camp and that an outside vendor had set up the zip line.

“The YMCA of Metropolitan Washington has been notified that a participant at a private event hosted by an outside organization on the property of the YMCA Camp Letts Retreat Center was injured,” a spokesperson said in a statement. “The YMCA has received a report that a youth guest fell while using a zip line provided by an outside vendor specifically for the event. The Y is praying for the participant’s full recovery.”
