Of California's fourteeners, only one is a volcano, Mount Shasta.  The other volcano in California is Lassen Peak.  They are part of the same string of volcanoes called the Cascade Volcanoes.  The Cascades run North through Oregon and Washington and into Canada.  They are part of the Pacific Ring of Fire.  The Ring of Fire refers to the areas around the Pacific Ocean that are or have been volcanically active.  Mount Fuji in Japan is another famous star in this constellation.
    Other famous volcanoes are Mount Saint Helens in Washington.  Mount Hood near Portland, Oregon.  And the very ominous Mount Rainier near Seattle.  When I saw Rainier for the first time I was filled with a sense of awe and  fear.  Really.  I saw the mountain over the Seattle skyline and I got the gut feeling, a sense, that this shape was unstable.  The massive form appears to me on the verge of collapse.   I later read an article about the geology inside the mountain.  It is literally rotting inside because of the chemistry of escaping gases and melted snow.  I want to summit this mountain before it's beauty changes.  Remember that Saint Helens, once a perfect cone, is now a hollow shell.
    My desire is to summit a few of these volcanoes as well as all of California's fourteeners.  The Cascade Volcanoes are listed below.
