The Cascades organization was formed in 1957 as the Greenwood Boys Club Corps, becoming the Seattle Thunderbirds the next year. A split in 1966 saw many members join the new Cascade Cadets, which changed its name to Seattle Cascades in 1970. The corps won the Drum Corps International Division III World Championship title in 2000, and then doubled its size to compete in Division II in 2001. In 2002, they became the first Pacific Northwest corps to become a Division I finalist.
