Lassen Volcanic

Lassen Volcanic National Park was established in 1916, the 11th of America's National Parks to be designated. Located in northern California, the area is rich in hydrothermal sites like Bumpass Hell, with its acres of bubbling mud pots. The summit of Lassen Peak Volcano offers stellar views of the surrounding wilderness. Nearby, the Devastated Area is littered with lava rocks from its last major eruptions, which occurred between 1915 and 1917.
