BEAR, DELAWARE — Officials are investigating the death of a 59-year-old woman who died at a popular adventure park after falling from a zipline. <br /> <br />The unidentified 59-year-old was reportedly visiting the Go Ape adventure course in Lum Ponds State Park on Wednesday afternoon. She was riding one of the park’s ziplines when she fell some 40-feet to her death, WPVI-TV ABC Action News reported, citing police. <br /> <br />On its website, Go Ape says it gives patrons a 30-minute safety lesson before they venture into the park. During this time they teach visitors how to use equipment — including pulleys and harnesses — and other safety gear. After this visitors are left to enjoy the park by themselves, but instructors patrol the forest regularly. <br /> <br />Police are still investigating the circumstances of the woman’s death. WPVI-TV ABC Action News reports that paramedics performed CPR while traveling to a local hospital following the accident where she was later pronounced dead.
