Mount Lassen is seen with a foreground of Upper Meadow and Kings Creek, shortly before parking for the summit trail. 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.
