Mount St. Helens [SEP] Protection and later history
In 1982, President Ronald Reagan and the U.S. Congress established the Mount St. Helens National Volcanic Monument, a area around the mountain and within the Gifford Pinchot National Forest. Following the 1980 eruption, the area was left to gradually return to its natural state. In 1987, the U.S. Forest Service reopened the mountain to climbing. It remained open until 2004 when renewed activity caused the closure of the area around the mountain (see "Geological history" section above for more details). Most notable was the closure of the Monitor Ridge trail, which previously let up to 100 permitted hikers per day climb to the summit.
