The ride, which opened in 2017, "drops riders 110 feet down inside the mountain as they listen to ghostly mining tales from days gone by," according to the park's website. It's been dubbed the "world’s first drop ride to go underground."  

The Garfield County Coroner’s Office is currently conducting the investigation alongside the Garfield County Sheriff’s Office. 

The park confirmed that the investigation will include state and local authorities, independent engineering and ride inspection experts. The park's maintenance team is also involved in the investigation.
