Big Dipper was a wooden roller coaster located at the defunct Geauga Lake amusement park in Bainbridge Township, Ohio. Originally opened in 1925 as Sky Rocket, it was renamed Clipper in the late 1940s and eventually Big Dipper in 1969. It was the oldest operating roller coaster in Ohio and seventh-oldest in the United States when it closed in 2007. Designed by John A. Miller, the Big Dipper was also one of the last remaining roller coasters in the world from the legendary designer. American Coaster Enthusiasts awarded the coaster its ACE Coaster Classic and ACE Coaster Landmark designations. Efforts to sell, preserve, and restore the ride were unsuccessful. The ride was demolished on October 17, 2016.
