Mount St. Helens Volcano, Washington
Mount St. Helens is located in southern Washington, about 100 miles south of Seattle and 50 miles north of Portland, Oregon. The late part of September early October 2004 brought a renewed amout of seismic and volcanic activity. The activity led up to a series volcanic 'burps' in early October. Scientists are still monitoring the volcanic activity. As of mid-2005, the observatories have reopened so that visitors may view the volcano.
