Crater Lake Crater Lake (Klamath: giiwas) is a caldera lake in south-central Oregon in the western United States.

Mazama Ash The Mazama Ash is a large geologically recent volcanic ash deposit that covers portions of the U.S. states of California, Oregon, Washington, Idaho, Montana, Nevada, Wyoming and Utah, as well as the Canadian provinces of British Columbia, Alberta and southwestern Saskatchewan. It was created by a massive explosive eruption of Mount Mazama ~6,900 years ago, during which it collapsed to create the caldera of Crater Lake.
