The woman killed after she fell from a platform at the Lums Pond State Park in Delaware has been identified as Tina Werner, 59, of Felton.
The tragedy happened at about 2:35pm Wednesday, when Werner was on the Go Ape Aerial Rope Adventure Course in the park in Bear.
Delaware State Police say Werner was standing on a platform about 35 feet above the ground, waiting to descend on a zip line.
That's when she fell from the platform to the ground.
Go Ape employees, park rangers, and then paramedics tried first aid and advanced life-saving efforts, but Werner was pronounced dead at the hospital.
The Division of Forensic Sciences will perform an autopsy.
Nobody else was injured.
Police say the investigation into what happened is still going on, but foul play is not suspected at this time.
According to The Associated Press, participants at Go Ape courses are equipped with climbing harnesses, and two sets of safety ropes with carabiners, that they clip and unclip to wires as they move through the trees. The course in Bear spans seven acres and includes four zip lines and a variety of swings, rope ladders, bridges and trapezes.
