Mount St. Helens is a world-famous stratovolcano in the Cascade Range of Washington state. It erupted catastrophically on May 18, 1980, transforming the landscape with a massive debris avalanche, ash plume, and subsequent lava and ash flows. Today, the volcano is a site of ongoing geological change, with a crescent-shaped crater, deep Spirit Lake, and regenerating forests around the blast zone. Key points for visitors include the Johnson Ridge Observatory, which provides dramatic high-elevation views of the crater; the Gifford Pinchot Visitor Center near Castle Rock, offering exhibits and ranger programs; and various trails leading to viewpoints and landforms—note that trail access is subject to closure depending on volcanic activity and safety advisories. The surrounding landscape features high-elevation wilderness and rivers tied to volcanic runoff, and nearby facilities and towns serve as bases for day trips. Whether you're into hiking, geology, or photography, Mount St. Helens offers a visceral window into planetary forces and recovery over the past four decades.
