Crater Lake National Park Location
Crater Lake National Park is located in the state of Oregon. The lake is remarkable for being situated in the caldera of a collapsed volcano, Mount Mazama, which erupted approximately 7,000 years ago.
This event is supported by geological evidence and corresponds with Indigenous oral traditions of the area that recount the explosive history of the volcano, recognized in stories involving Moy Yaina (Mount Mazama) and Mlaiksi (Mount Shasta). These tales illustrate the awareness Indigenous peoples had of the geological changes around them, including volcanic eruptions and other natural events.
