The place
Lassen Peak blew in 1915 and Congress made it a national park the following year while the ground was still warm. It remains the southern anchor of the Cascade Range and one of the most likely volcanoes in the chain to erupt again. The park holds all four types of volcanoes found on earth, plug dome, shield, cinder cone, and composite, plus bubbling mud pots and fumaroles that smell like the whole place is still making up its mind.
Established 1916. About 420,000/year visitors.
