An investigation is underway after a 6yearold girl died on a ride at the Glenwood Caverns Adventure Park in Colorado. The child was riding the Haunted Mine Drop, which drops riders "110feet inside the dark depths of Iron Mountain in what feels like a freefall.” Walt Stowe, a spokesman for the Garfield County Sheriff’s Office, said that his agency is investigating the accident and opted to not give any additional information, according to the outlet.
