What Does Mt St Helens Look Like Now

The eruption of Mount St. Helens on May 18, 1980, dramatically reshaped the landscape of southwestern Washington State. What was once a symmetrical, snow-capped peak transformed into a scarred and significantly shorter mountain. But what does Mount St. Helens look like now, more than four decades after that cataclysmic event? The answer is complex, revealing a story of destruction, resilience, and ongoing scientific discovery.

A Mountain Reborn: What to Expect Today

Visiting Mount St. Helens today is an awe-inspiring experience. The landscape is a powerful testament to nature's destructive force, but also to its remarkable ability to heal and regenerate. Here's a glimpse of what you can expect:

The Crater: The most striking feature is the massive, horseshoe-shaped crater that dominates the north face of the mountain. This gaping void, formed by the lateral blast and subsequent collapse of the summit, is a constant reminder of the eruption's intensity.
The Lava Dome: Within the crater, a lava dome has been steadily growing since the mid-1980s. This dome, a mound of thick, cooling lava, represents the ongoing volcanic activity beneath the surface. Its presence is a clear indication that Mount St. Helens is still an active volcano.
The Pumice Plain: To the north of the mountain stretches the pumice plain, a vast expanse of grayish-white volcanic debris deposited during the eruption. This seemingly barren landscape is slowly being recolonized by plants and animals, demonstrating the early stages of ecological succession.
Spirit Lake: Once a pristine alpine lake nestled at the foot of Mount St. Helens, Spirit Lake was dramatically altered by the eruption. A massive debris avalanche surged into the lake, raising its surface level and creating a floating log mat composed of countless trees uprooted by the blast.
The Blast Zone: The surrounding forests bear the scars of the eruption, with vast areas of downed trees and scorched earth. However, even in these devastated zones, life is slowly returning, with wildflowers, shrubs, and young trees beginning to reclaim the land.

The Anatomy of a Transformed Landscape

To truly understand what Mount St. Helens looks like now, it's essential to delve deeper into the specific features that define its transformed landscape:

The Crater and Lava Dome: A Window into the Earth

The crater is the most prominent and visually arresting feature of Mount St. Helens. It's a stark reminder of the power of volcanic eruptions and the immense forces at play beneath the Earth's surface. Its formation was a two-stage process:

The Lateral Blast: The initial eruption was a lateral blast, a sideways explosion of hot gas and rock that ripped through the north face of the mountain. This blast removed a significant portion of the summit, creating a large opening.
The Summit Collapse: Following the lateral blast, the weakened summit collapsed into the void, further enlarging the crater and creating its distinctive horseshoe shape.

Within the crater, the lava dome is a testament to the ongoing volcanic activity. It's formed by the slow extrusion of viscous lava onto the crater floor. The dome has grown intermittently since 1980, with periods of rapid growth followed by periods of quiescence. Scientists closely monitor the dome for changes in its shape, size, and gas emissions, as these can provide clues about the volcano's internal state and the potential for future eruptions. The dome is not solid rock, but rather a crumbly and unstable mass.

The Pumice Plain: A Blank Canvas for Life

The pumice plain is a vast expanse of volcanic debris that stretches north of Mount St. Helens. It was formed by the deposition of pumice, ash, and other volcanic materials during the eruption. The pumice plain is a relatively barren landscape, but it's far from lifeless. It represents a unique opportunity for scientists to study the processes of ecological succession, the gradual process by which ecosystems recover after a disturbance.

Early Colonizers: The first organisms to colonize the pumice plain were typically hardy plants, such as lupines and fireweed, that are adapted to harsh conditions. These plants help to stabilize the soil and provide nutrients for other organisms.
Animal Life: Animals, such as pocket gophers, also play an important role in the recovery of the pumice plain. They help to aerate the soil and disperse seeds.
A Long Road Ahead: The pumice plain is still in the early stages of ecological succession, and it will take many years for it to fully recover. However, the progress that has already been made is a testament to the resilience of nature.

Spirit Lake: A Living Laboratory

Spirit Lake was dramatically altered by the eruption of Mount St. Helens. The debris avalanche that surged into the lake raised its surface level by nearly 200 feet and created a floating log mat composed of countless trees uprooted by the blast. The lake was initially devoid of life, but it has slowly begun to recover.

The Log Mat: The floating log mat is a unique feature of Spirit Lake. It provides habitat for a variety of organisms, including insects, amphibians, and birds.
Bacterial Activity: The lake is also home to a thriving community of bacteria, which play an important role in the decomposition of organic matter.
A Cautionary Tale: Spirit Lake serves as a reminder of the potential for volcanic eruptions to drastically alter aquatic ecosystems. However, it also demonstrates the resilience of life and the ability of ecosystems to recover, even after severe disturbances.

The Blast Zone: A Mosaic of Destruction and Recovery

The blast zone surrounding Mount St. Helens is a mosaic of destruction and recovery. Some areas were completely devastated by the eruption, while others were less affected. The severity of the damage depended on the distance from the volcano and the direction of the blast.

Downed Trees: In the areas closest to the volcano, virtually all of the trees were flattened by the blast. These downed trees provide habitat for a variety of organisms, including insects, fungi, and small mammals.
Wildflowers and Shrubs: In areas that were less severely affected, wildflowers and shrubs have begun to recolonize the land. These plants help to stabilize the soil and provide food for animals.
Forest Regeneration: Over time, the forests surrounding Mount St. Helens will gradually regenerate. However, the process will take many years, and the forests may never be exactly the same as they were before the eruption.

Scientific Insights: What We've Learned

The eruption of Mount St. Helens provided scientists with an unprecedented opportunity to study volcanic processes and ecological recovery. The insights gained from this event have revolutionized our understanding of these phenomena:
