Mount St. Helens, located in Washington, famously erupted in 1980, causing significant destruction and reshaping the surrounding landscape.

Mount St. Helens is an active stratovolcano located in the Cascade Range in Washington. It is most famous for its catastrophic eruption on May 18, 1980, which was one of the most significant volcanic events in U.S. history. The eruption caused a massive debris avalanche, followed by an explosive lateral blast that reduced the mountain's height and left a large crater. The eruption also led to the loss of 57 lives and caused widespread environmental and economic damage. Today, the area is a national monument and is monitored closely for volcanic activity, drawing both scientists and tourists.
