Detailed explanation-1: -Established in 1902, Crater Lake is the fifth-oldest national park in the United States and the only national park in Oregon. The park encompasses the caldera of Crater Lake, a remnant of Mount Mazama, a destroyed volcano, and the surrounding hills and forests.
Detailed explanation-2: -Crater Lake partially fills a type of volcanic depression called a caldera that formed by the collapse of a 3, 700 m (12, 000 ft) volcano known as Mount Mazama during an enormous eruption approximately 7, 700 years ago.
Detailed explanation-3: -Crater lakes are volcanic lakes found in craters and calderas. Crater lakes usually form through the accumulation of rain, snow and ice melt, and groundwater in volcanic craters. Crater lakes can contain fresh water or be warm and highly acidic from hydrothermal fluids.
Detailed explanation-4: -The blue beauty of Crater Lake extends beyond its depth. At 1, 943 feet deep, Crater Lake is the deepest lake in America. Famous for its beautiful blue color, the lake’s water comes directly from snow or rain–there are no inlets from other water sources.
