May 18, 1980: Mount St. Helens erupts, leaves a mess of documents

By James Lewis on May 18, 2010

Thirty years ago today, Mount St. Helens erupted in Washington on the Gifford Pinchot National Forest and left an altered landscape as well as a mess of historical documents in its wake.  The deadliest volcanic event in U.S. history flattened 200 square miles of forest on the surrounding private and public lands.  Its impact on forest management is still reverberating across the pages of history and forestry textbooks to this day.

FHS has a plethora of documents and historical photos of the still-active volcano in different parts of our archive and library.  In addition to numerous journals and magazines in our library with articles on the topic, the federal government (in particular the Forest Service) generated documents and reports on what happened before, during, and after the event. We also have coverage of the ensuing debate over what it should do with its share of the land — whether the timber should be salvaged and the forest replanted or if it should be left alone and studied.  Many of these items, along with oral history interviews with agency personnel, can be found in our U.S. Forest Service History Collection, which is searchable through our database.  After much debate, which can be followed via our documents, the area became a natural laboratory and a 110,000-acre national monument with two visitors centers (we even have information on those!).

Don’t want to read through all of that stuff?  You can learn more about the impact of the eruption on the Forest Service’s land management practices in the film “The Greatest Good” and from a DVD extra, as well as the companion book The Forest Service and The Greatest Good.  We also have several photos in the FHS collection like the one seen here of Mount St. Helens before it exploded.

The Weyerhaeuser Company, which owned quite a bit of land adjacent to the volcano also affected by the eruption, had to make similar decisions about what to do with its timberland. You can find two articles that touch on the company’s response to the eruption here and here, with “before” and “after” photos on page 26 of the second article.

In light of current debates about whether the Forest Service land under study should be turned over to the National Park Service and reopened for recreation, it may be useful to revisit the history of Mount St. Helens and the legacy of the eruption thirty years ago today.
