Mount St Helens, located in southern Washington State, is one of the most famous active volcanoes in the United States. It is part of the Cascade Range and is known for its explosive eruption on May 18,1980, one of the most significant volcanic events in US history.
The eruption was preceded by smaller earthquakes and steam explosions, which caused the mountain’s north face to collapse, triggering a massive landslide. This landslide and eruption resulted in an explosive release of gas, ash and magma, creating a violent pyroclastic flow and destroying much of the surrounding landscape. The eruption was so powerful that it reduced the mountain’s elevation by about 1,300ft (400m) and left behind a dramatic crater.
Since the eruption, the area around Mount St Helens has undergone a remarkable recovery, with new plant and animal life returning to the region. The landscape has evolved, forests gradually regrowing and the crater has become a unique and fascinating geological feature.
Keen hikers can climb to the crater, tackling an elevation of 4,500ft (1,372m). The effort pays off with stunning views of nearby peaks of Mount Hood, Mount Adams and Mount Ranier. However, hikers must be well-prepared, as unpredictable weather can turn rain into snow, quickly creating whiteout conditions.
