A diagram of the climbing routes on the South face of Mount St. Helens.  From the Climber's Bivouac at 3,780 feet, the nearly 4,500 foot elevation gain on the Monitor Ridge route (green) meets the longer Marble Mountain route (blue) near the summit at 8,270 feet.  The "true" summit at 8,365 feet is nearly 1/2 mile to the West.
