The Science & Learning Center (SLC) is a collaborative effort between the Mount St. Helens Institute and the U.S. Forest Service at Mount St. Helens National Volcanic Monument. Together, our goal is to connect people with nature through science, the arts, and adventure recreation. Our facilities and programs are designed to extend the quality and duration of educational experiences both onsite at the volcano and through engaging online experiences.
