3. Mount St. Helens Visitor Center

The Mount St. Helens Visitor Center opened its doors to the public a few years after the monumental eruption of Mount St. Helens. Functioning as a gateway to the mountain, over 30 miles away, the Visitor Center's goal is to educate visitors on the historical significance of the landscape before and during the eruption. The center also focuses on the resulting impact on nearby ecosystems. The vantage point offers a view of the Western slope of the mountain, visible from both the center and walking trail.

Today, you can almost see a line between the trees that were farmed and the natural regeneration of plant-life at the mountain.
