Mount St. Helens

Mount St. Helens stands as one of America's most intriguing cryptid hotspots, where the legendary Bigfoot allegedly roams the rugged volcanic landscape. Following Expedition Unknown's investigation into recent sightings and compelling evidence, this Washington state destination offers adventurers a chance to explore the same mysterious terrain where Native American legends and modern encounters converge.

Mount St. Helens is an active stratovolcano in Skamania County, Washington, part of the Cascade Volcanic Arc and the Pacific Ring of Fire. The mountain lies 52 miles northeast of Portland, Oregon, and is best known for its catastrophic eruption on May 18, 1980, which reduced the summit elevation from 9,677 feet to 8,363 feet and created a 1-mile-wide horseshoe-shaped crater. The blast killed 57 people and destroyed 185 miles of highway, making it the most economically destructive volcanic event in U.S. history. Beyond its geological significance, the Mount St. Helens area has long been associated with Bigfoot sightings and Native American legends, drawing the Expedition X team to investigate reported cryptid encounters in the volcano's rugged, recovering wilderness.

What Experts Say

Mount St. Helens holds dual significance as both a geologically active site and a cryptozoological hotspot. The Cowlitz people knew the volcano as Lawetlat'la, while the Klickitat called it Loowit or Louwala-Clough, and local Native American traditions include legends that some researchers have connected to Bigfoot lore. The dramatic 1980 eruption fundamentally altered the landscape, triggering a massive debris avalanche of 0.6 cubic miles in volume after a magnitude 5.1 earthquake, and the recovering wilderness has become increasingly associated with cryptid sightings in recent decades.

Geologists continue to monitor Mount St. Helens closely, predicting that future eruptions will likely be more destructive due to the current configuration of lava domes requiring greater pressure to erupt. The volcano experienced continuous activity from 1980 until 2008, and its status as an active stratovolcano means the terrain remains dynamic and potentially hazardous. The ecosystems disrupted by the 1980 blast have largely recovered—most lakes returned to normal states within six years, with aquatic life actually benefiting from ash deposits—but the landscape bears permanent scars from the eruption.

The Expedition X investigation explored whether the remote, rugged terrain around Mount St. Helens could support an undiscovered primate population, examining reported encounters in the context of the area's ecological recovery and long tradition of cryptid stories. The episode approached the subject with the team's characteristic evidence-based methodology, navigating dangerous volcanic terrain while gathering witness accounts and environmental data. As with many cryptozoological investigations, the team's work documented the cultural significance of Bigfoot legends in the Pacific Northwest while searching for physical evidence that remains elusive.

Fun Facts

The 1980 eruption's debris avalanche was triggered by a magnitude 5.1 earthquake and reduced the mountain's elevation by 1,314 feet in a matter of minutes

Aquatic ecosystems near the volcano actually benefited from the eruption, with ash deposits allowing life to multiply rapidly in area lakes

The volcano is named after British diplomat Alleyne FitzHerbert, 1st Baron St Helens, who never actually visited the mountain

Mount St. Helens experienced continuous volcanic activity for 28 years after the 1980 eruption, finally quieting in 2008

Planning a Visit

Getting There

Mount St. Helens National Volcanic Monument welcomes visitors year-round, with multiple visitor centers, hiking trails, and climbing routes accessible to the public. The mountain remains a popular hiking and climbing destination despite its active status, though visitors should check current conditions and permits requirements with the U.S. Forest Service. The Johnston Ridge Observatory offers dramatic views of the crater and blast zone approximately 5 miles from the summit.

Nearest City

Portland, Oregon, approximately 52 miles to the southwest, or Seattle, Washington, approximately 98 miles to the north.

Best Time to Visit

Summer months (July through September) offer the most reliable weather and road access, with many trails and facilities closed or limited during winter. Climbers typically attempt the summit between May and September when snow conditions are most stable.

Visitor Highlights

  • Explore volcanic terrain linked to numerous Bigfoot sightings and encounters
  • Discover Native American legends and cultural connections to the cryptid
  • Hike challenging trails through the blast zone and old-growth forests
  • Visit the Johnston Ridge Observatory for panoramic views of the investigation area

Best time to visit: Late spring through early fall (May-October) offers the best weather conditions and trail access, though winter visits provide a more mysterious, snow-covered atmosphere.

Travel tip: Bring sturdy hiking boots and layers as weather conditions can change rapidly in the volcanic terrain, and always inform others of your hiking plans before venturing into remote areas.
