A VISITOR’S GUIDE TO MOUNT ST. HELENS NATIONAL VOLCANIC MONUMENT
30th Year Commemorative Edition Volcano ReView
Thirty Years of Change: A Landscape Transformed! It is hard to believe that 30 years have passed since the May 18, 1980 eruption. Anniversaries are a time to look back and mark the changes that have occurred over the span of time. The one thing we know here at the Monument is that nothing is certain but change. At Mount St. Helens, what changes we have witnessed! The landscape has shifted dramatically from a gray, still and nearly barren panorama to an environment that is green, active and life-filled. The volcano, not to be over shadowed, has added two lava domes and North America’s youngest glacier, while providing a window into some of the most spectacular geologic processes in the country. Throughout the thirty years, the U.S. Forest Service has worked hard to protect the unique features of the Monument and allow natural processes to continue substantially unimpeded. If Mount St. Helens has taught us one lesson it is never underestimate nature’s ability to change. We have been so fortunate to witness these changes and learn lessons in the process.

The Disappearing Blown Down Forest: One of the most enduring memories of the May 18, 1980 eruption is the vast maze of trees strewn across the landscape by the powerful lateral blast. Today’s blown down forest is difficult to see for reasons beyond our imagination. The weight of the snow packs each year push the trunks into the ground and soaks the trees, while the summer sun bakes them. The intense wetting and drying has led to the rapid deterioration of the blown down trees. Windblown seeds caught by the moist, nutrient-rich tree trunks nourished seedlings and created a veil of low-lying grasses and shrubs. The array of plants and animals that survived the eruption also made it easier for other life to colonize this decimated area. Today, the blown forest is hidden by an odd assortment of silver fir, huckleberry and other pre- eruption forest survivors, beside sun-loving weeds and shrubs.

We Invite You to Explore and Help Protect one of Nature’s Youngest and Most Dynamic Landscapes The Mount St. Helens National Volcanic Monument was established by Congress in 1982 to protect natural features and processes and provide access for recreation, research and education. The monument has become an internationally renowned laboratory for the study of earth processes and ecosystem recovery following large-scale disturbance. The quality and duration of data collected here over the last 29 years is unparalleled and the volcano continues to attract scientists, teachers, and students from around the world. As you explore, look for evidence of the 1980 eruption and observe plants and animals E. Mikkelson that are thriving in a forest shattered by volcanic eruption. As you enjoy the wonder of
