Crater Lake Oregon, from GOZooM.

Crater Lake, is a caldera lake located in the south-central region of the U.S. state of Oregon. The lake partly fills a nearly 2,148-foot (655 m) deep caldera that was formed around 7,700 (± 150) years ago by the collapse of the volcano Mount Mazama. The eruption dispersed almost 70 cubic kilometres of the mountain over western North America.

When Mount Mazama erupted 6800 years ago creating Crater Lake, it dispersed almost 70 cubic kilometres of the mountain over western North America. The ash layer from this eruption is visible here in the background located in the city of Edmonton on the shore of the North Saskatchewan River.
