Mount St. Helens is found in Skamania County in Washington State and is one of the active stratovolcanoes of the world. Its location in Skamania County puts it 50 miles to the northeast of Portland and 96 miles to the south of Seattle. This volcano is part of the Cascade Range and during the current Holocene period, it has actually been the most active in this range. In addition to being the most active, scientists predict that it is the most likely to erupt of all of the volcanoes found in the United States. The volcano has an elevation of 8,363 feet and contains a horseshoe-shaped crater which developed during its most famous eruption in 1980.
