Mount Lassen National Park
9. Bernice at Bumpass Hell
Lassen geothermal area, the Sulfur works, Bumpass Hell (largest), Little Hot Springs Valley, Boiling Springs Lake, Devils Kitchen, and Terminal Geyser - offer bubbling mud pots, steaming fumaroles, and boiling water. Some of these thermal features are getting hotter. Scientists think that Lassen Volcanic National Park and Mount Shasta are the most likely candidates in the Cascades to join Mount Saint Helens as active volcanoes.
Lassen Volcanic National Park is but one of the active, dormant, or extinct volcanoes that extend around the Pacific Ocean in a great Ring of Fire. This zone of volcanoes and earthquakes marks the edges of plates that form the Earth's crust. Volcanic and seismic disturbances occur as these great slabs override or grind past each other.On to Page 10   Back to Page 8
