The crater at Mount St. Helens is about 1.2 miles (1.9 km) in diameter. It was created during the catastrophic eruption in 1980, which also caused the summit of the mountain to collapse.

Mount St. Helens is not a crater inside a crater, but rather a stratovolcano that experienced a major eruption in 1980, which resulted in the formation of a large crater at its summit. This crater, known as the "summit crater," was created when the volcanic cone collapsed after the eruption. The mountain itself has a complex geological history, but it is primarily characterized by its single large summit crater rather than a nested crater structure.
