Is Mount St Helens a crater inside a crater?
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.
