Highlights

  • Lassen Peak is the southernmost active volcano in the Cascade Range.
  • Lassen rises 2,000 feet above the surrounding terrain and has a volume of half a cubic mile, making it one of the largest lava domes on Earth.
  • Lassen Peak has the distinction of being the only volcano in the Cascades other than Mount St. Helens to erupt during the 20th century.
  • On May 22, 1915, a powerful explosive eruption at Lassen Peak devastated nearby areas and rained volcanic ash as far away as 200 miles east.
  • Unlike most lava domes, Lassen Peak is topped by craters.
  • Lassen Peak has the highest known winter snowfall amounts in California, with annual snowfalls reaching more than 1,000 inches in some years at its base at "Lake Helen".
  • A well-maintained class 1 route leads to the summit from Lake Helen.
  • Lassen Peak is the highest point in Lassen Volcanic National Park and in Shasta County.
