Lagoon is an amusement park in Farmington, Utah, United States located about seventeen miles (27 km) north of Salt Lake City. It is privately owned. It has nine roller coasters, four of which are unique; one of these being Colossus the Fire Dragon, which is the only Schwarzkopf Double Looping coaster still in operation (Laser at Dorney Park closed at the end of the 2008 season). The second unique coaster is Roller Coaster, one of the oldest coasters in the world operating since 1921. The third is the park's largest and fastest coaster, Wicked (2007). It was designed by Lagoon's engineering department and Werner Stengel in cooperation with Zierer, a ride manufacturer.
