Volcano: The Blast Coaster

Volcano: The Blast Coaster, or simply Volcano, was an inverted roller coaster located at Kings Dominion in Doswell, Virginia. Designed by Werner Stengel, it was the first launched roller coaster manufactured by Intamin and the first of its kind in the world to be inverted. Its launch mechanism was based on linear induction motor technology. After a series of delays, Volcano officially opened to the public on August 3, 1998. The ride's soft opening was held two days earlier on August 1. A portion of the ride was enclosed inside a man-made volcano, which previously housed other attractions and was constructed in 1979. Volcano's final year of operation was in 2018, and in the off-season that followed, Kings Dominion made the sudden decision to retire the roller coaster.

A man-made mountain, originally called The Lost World, was constructed at Kings Dominion in 1979. It was located in the Safari Village section of the park and featured three rides inside – a dark ride named Land of the Dooz, a flume ride named Voyage to Atlantis, and a Rotor flat ride from Chance Rides named Time Shaft. Voyage to Atlantis was renamed Haunted River for the 1980 season. In 1984, Land of the Dooz was refurbished and rethemed to The Smurfs franchise, becoming known as Smurf Mountain. As popularity declined over the years, Smurf Mountain eventually closed permanently in 1993. The other two attractions were closed after the 1994 season, and the mountain's entrance was sealed off, casting uncertainty on the enclosed area's future.
