It is a caldera ( a crater formed by volcanic explosion or by collapse of a volcanic cone.) With a diameter of 6.1 miles East to West and 4.7 miles North to South, an area of 20.42 sq miles, it is one of the deepest in the United States with a height of 1943 feet and holding 4.9 trillion gallons of water. Crater Lake was formed when a massive eruption of Mount Mazama 7700 years ago caused the mountain to collapse, leaving a steaming caldera. Centuries of rain and snow filled the caldera creating Crater Lake.
