Crater Lake is called Giiwas in the Klamath language. [7] Steel had helped map Crater Lake in 1886 with Clarence Dutton of the United States Geological Survey. The conservation movement in the United States was gaining traction, so Steel's efforts to preserve the Mazama area were achieved on two scales, first with the creation of the local ...

Crater Lake actually started as a mountain, Mount Mazama. A volcanic eruption roughly 7,700 years ago caused the mountain to collapse inward over time, forming a volcanic crater, the park says.
The National Park Service estimates that between 500,000 to 750,000 people visit Crater Lake every year. The lake is said to have formed after the eruption of a massive volcano more than 7,000 ...
Wizard Island was created after Mount Mazama, a large complex volcano, erupted violently approximately 7,700 years ago, forming its caldera which now contains Crater Lake. Following the cataclysmic caldera-forming eruption, which left a hole about 4,000 feet (1,200 m) deep where the mountain had once stood, a series of smaller eruptions over ...
The volcano also erupted in June about a mile south of Kilauea caldera, marking the first eruption in that region of the volcano in about 50 years. The last one took place in December 1974. The ...
However, past eruptions in this volcanic arc have multiple examples of sub-plinian eruptions or higher: Crater Lake's last eruption as Mount Mazama was large enough to cause its cone to collapse, [58] and Mount Rainier's closest neighbor, Mount St. Helens, produced the largest recorded eruption in the continental United States when it erupted ...
