Answer:
Crater Lake in southern Oregon is not a crater but actually a caldera.
Explanation:
Crater Lake is located in southwestern Oregon near Klamath Falls. Almost 600 m deep, this lake lies in the caldera of an already extinct volcano. Its name comes from a small crater situated on an island of this lake, Wizard Island. Since 1902 this lake has been part of Crater Lake National Park, a United States tourist attraction.
