Mount St. Helens National Volcanic Monument

Mount St. Helens National Volcanic Monument

Mt. St. Helens is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States. It is 50 miles (80 km) northeast of Portland, Oregon and 96 miles (154 km) south of Seattle, Washington. The volcano is located in the Cascade Range and is part of the Cascade Volcanic Arc, a segment of the Pacific Ring of Fire that includes over 160 active volcanoes. This volcano is well known for its ash explosions and pyroclastic flows.

Mount St Helens Environment Info

Mount St. Helens National Volcanic Monument is a U.S. National Monument that includes the area around Mount St. Helens in Washington. It was established on August 27, 1982 by U.S. President Ronald Reagan following the 1980 eruption. The 110,000 acre (445 km2) National Volcanic Monument was set aside for research, recreation, and education. Inside the Monument, the environment is left to respond naturally to the disturbance.

Mount St. Helens National Volcanic Monument was the United States' first such monument managed by the U.S. Forest Service. At dedication ceremonies on May 18, 1983. It has many trails, viewpoints, information stations, campgrounds, and picnic areas have been established to accommodate the increasing number of visitors each year.

Mount St. Helens is most notorious for its major 1980 eruption, the deadliest and most economically destructive volcanic event in the history of the United States. Fifty-seven people were killed; 250 homes, 47 bridges, 15 miles (24 km) of railways, and 185 miles (298 km) of highway were destroyed. A massive debris avalanche triggered by an earthquake measuring 5.1 on the Richter scale caused an eruption that reduced the elevation of the mountain's summit from 9,677 ft (2,950 m) to 8,363 ft (2,549 m), leaving a 1 mile (1.6 km) wide horseshoe-shaped crater. The debris avalanche was up to 0.7 cubic miles (2.9 km3) in volume. The Mount St. Helens National Volcanic Monument was created to preserve the volcano and allow for the eruption's aftermath to be scientifically studied.

The Johnston Ridge Observatory is located 52 miles (84 km) east of Castle Rock, Washington, at the end of Washington State Route 504, four miles from the mountain. Exhibits focus on the geologic history of the volcano, eyewitness accounts of the explosion, and the science of monitoring volcanic activity. Two movies and ranger-led programs are available every hour. A half-mile paved trail provides views of the lava dome, crater, pumice plain, and landslide deposit, with access to hiking trails in the restricted area.

The observatory is located near the site of volcanologist David A. Johnston's camp on the morning of May 18, 1980, and opened in 1993. It offers grand views of Mount St. Helens and much of the 1980 blast zone.

Windy Ridge is the closest view point accessible to the general public. Beginning in the summer of 1983, visitors have been able to drive to Windy Ridge, on U.S. Forest Service Road 99, only 4 miles (6.4 km) northeast of the crater. From this vantage point overlooking Spirit Lake, people see firsthand not only the evidence of a volcano's destruction, but also the remarkable, gradual (but faster than originally predicted) recovery of the land as revegetation proceeds and wildlife returns.
