In the program notes for the symphony, Hovhaness wrote:When Mount St. Helens erupted on the morning of May 18, 1980, the sonic boom struck our south windows. Ashes did not come here at that time but covered land to the east all across the State of Washington into Montana. Ashes continued to travel all around the world, landing lightly on our house a week later, after their journey all around our planet. In my Mount St. Helens Symphony I have tried to suggest a musical tribute to the sublime grandeur and beauty of Mount St. Helens and the surrounding majestic Cascade Mountains.
