"Thunderhawk is an inverted steel roller coaster at Michigan's Adventure amusement park in Muskegon, Michigan, United States designed by Vekoma of The Netherlands. The coaster was built in 1998 as Serial Thriller at Geauga Lake in Ohio and renamed Thunderhawk in 2004 when that park was purchased by Cedar Fair. After Geauga Lake closed in 2007, Thunderhawk was dismantled and moved to Michigan's Adventure for the 2008 season, where it became the first suspended looping roller coaster to ever be built in Michigan. Thunderhawk has a maximum height limit of 6 feet 8 inches (2.03 m). The ride is built on top of man-made land that is right on Adventure Lake."
