As the southern-most peak in the Cascade mountain range, Lassen Peak is the largest plug-dome volcano in the world. The park is actually the only one in the NPS to include all 4 types of volcanoes. And the surrounding areas have several geothermal features. The largest area of these features (Bumpass Hell) was closed due to reconstruction of the boardwalk. We still got to see the mudpots at Sulfur Works & the bubbling of the Cold Boiling Lake. The big surprise though was Kings Creek Falls – which was actually a very long water cascade.

These last pics are a series of shots taken during one of last eruptions in 1914 – it has had a few minor eruptions since then but stopped in 1921.
