It is also less tiring than a standing or crouching glissade in softer snow. Notable features are Mount Monolith, Tombstone Mountain, and Glissade Pass. The method is slower but more controlled than the standing glissade. However, neither Glissade nor Die Wildkatze were considered major roller coasters. Busch Gardens Williamsburg opened in 1975 with one roller coaster, Glissade. The standing glissade is best performed over firm snow with a soft top layer. This is known as a "glissade en tourant" in the Russian school. This is the easiest type of glissade and generally provides the greatest amount of stability. Glissade was a roller coaster located at Busch Gardens Williamsburg in Virginia.
