091509Lake Helen, Lassen Volcanic National Park1459Douglas Orton.jpg
Lake Helen lies at the base of Lassen Peak, one of the worlds largest plug dome volcanoes, last erupted in May, 1914. Called a miniature Yellowstone by many, mud pots, fumaroles and boiling water continue to this day. Lassen is part of the Pacific Ring of Fire. This view from Highway 89, which traverses the park, catches the highway as it skirts both Lake Helen and Lassen Peak.
