• Lassen Peak Volcano
  -- Geographic Setting, and Geologic and Eruptive History
  In May 1914 Lassen Peak burst into eruption, beginning a seven-year cycle of sporadic volcanic outbursts. The climax of the episode took place in 1915, when the peak blew an enormous mushroom cloud some seven miles into the stratosphere. The reawakening of this volcano, which began as a vent on a larger extinct volcano known as Tehama, profoundly altered the surrounding landscape. -- From: U.S. National Park Service Website, Geology Fieldnotes - Lassen Volcanic National Park, California, April 2000
