Caption: Huge crater left by Mount St. Helens eruption. The May 18, 1980, eruption of Mount St. Helens volcano in Washington State produced a crater at the mountain approximately one kilometer wide and two kilometers long. According to U.S. Geological Survey scientists, the atom bomb-like force of the main eruption also exploded out about 5,000 feet of the north face of the mountain and leveled trees in a 185 square mile area. The volcano last erupted 123 years ago. PIO No. 80-179.
