History
The creek valley at Charlestown is one of the oldest unglaciated streams in the state. Even though the stream was this way, melting water from northern glaciers helped shaped the streams deep valley's. The trip down Fourteenmile Creek shows the effects of the Ohio River on it and how it is the same elevation as the Ohio due to dams and locks along the Ohio. When the Ohio rises, Fourteenmile seems to be 'reversing' in its flow due to the water backing up.
The park was used as the Indiana Army Ammunition Plant for 50 years, ending in 1995. The park used to also have a turn of the century amusement park called Rose Island.
