This 110,000-acre monument area was created for research, recreation, and education. Inside the Monument, the environment is left to respond naturally to the disturbances created by the volcano.



It is most famous for the catastrophic eruption on May 18, 1980 at 8:32am. That eruption was the most deadly and economically destructive volcanic eruption in the history of the United States. Mount St. Helens and the surrounding landscape were dramatically changed within moments of the eruption. It resulted in the largest debris avalanche in recorded history, reducing its summit from 9,677 feet (2,950 m) to 8,364 feet (2,550 m) in elevation and replacing it with a mile-wide (1.5 km-wide) horseshoe-shaped crater . While climbing to the crater rim is permitted, entry into the crater is strictly prohibited.
