What Will You Discover?

Imagine walking on a boardwalk alongside bubbling pits of mud and hissing cracks in the earth. Steam rises from boiling pools and moistens your skin, and the smell of sulfur fills the air. A quiet squeak makes you look up and see a golden mantled squirrel perched on the handrail. Can you imagine this scene? Would you like to join this journey?

That is Some Hot Water!
Lassen Volcanic National Park is located in the northern section of California. The park is known for its many volcanoes and hydrothermal (hot water) features. Did you know that know all four types of volcanoes found on earth can be found at this one park? Or that the one of the hottest steam vents (fumaroles) in the world is here at Lassen? The hydrothermal areas in the park are examples of ongoing volcanic activity, and are reminders that Lassen is constantly changing.
