This documentary on the May 1980 eruption of Washington's Mount St. Helens volcano does a fine job of explaining why the mountain exploded, but what distinguishes this production is its spectacular cinematography. Originally shown in IMAX theaters, this film presents highly detailed and lavish views of the gorgeous scenery of the Pacific Northwest, both as they appeared before the top 1,300 feet of Mount St. Helens was blown into the sky and during the disaster's dramatic aftermath. When the first eruption occurred on the morning of May 18, 1980, the entire region was showered with gray ash, and the footage of towns that took on a wintry appearance in the springtime is truly eerie. For weeks after the mountain blew, it created its own unstable weather system, but when the clouds finally cleared and camera crews could fly near the volcano, the footage they brought back was stunning. Shots of what had been wooded mountainsides made utterly desolate are terrifying, and they dramatize how powerful and deadly a volcano can be. More recent footage showing the landscape after it recovered is inspiring and reassuring, and this film, which was nominated for an Academy Award, will leave viewers in awe of both the beauty and violent fury of Mount St. Helens.
