Before the Eruption:
* Volcanic cone: A symmetrical, cone-shaped mountain with a classic stratovolcano form.
* Glaciers and snowfields: Extensive glacial coverage, particularly on the north side, providing a pristine and rugged beauty.
* Forests: Lush forests of Douglas fir, western hemlock, and other coniferous trees, typical of the Pacific Northwest.
* Lakes and rivers: Several pristine lakes and rivers originating from the mountain's slopes.
After the Eruption:
* The Blast Zone: The area closest to the eruption is a stark, barren landscape.
* Crater: A horseshoe-shaped crater formed by the lateral blast, measuring about 1 mile wide and 2,000 feet deep.
* Debris flows and mudflows: Thick layers of volcanic debris and mud cover the valley floor.
* Burned trees: Large areas of dead and standing trees killed by the heat and blast.
* The Recovery Zone: Further away from the blast, the landscape gradually recovers.
* Regrowth: New vegetation, particularly grasses and wildflowers, is beginning to colonize the ash-covered areas.
* Succession: Pioneer species pave the way for a gradual return of trees and larger plants.
* Glacier rejuvenation: New glaciers are forming in the crater, filling with melted snow.
Key Features:
* The Pumice Plain: A large expanse of light-colored volcanic ash and pumice, stretching outwards from the crater.
* Spirit Lake: A lake dammed by debris flows, dramatically altered by the eruption.
* Johnston Ridge Observatory: A popular visitor center offering stunning views of the crater and surrounding landscape.
* The Ape Caves: A network of lava tubes formed by volcanic flows, popular for spelunking.
Overall, Mount St. Helens presents a unique landscape of contrast, showcasing the destructive power of nature and the resilient forces of regeneration. It is a place of awe-inspiring beauty, scientific study, and captivating natural history.
