Crater Lake National Park's foremost attraction is Crater Lake. Crater Lake was formed when Mount Mazama was destroyed by a volcanic eruption 7,700 years ago. It is estimated that this eruption was 42 times stronger then the blast from Mount Saint Helen's eruption. The result was a caldera which filled with water and became Crater Lake. The entire Mount Mazama lies within the boundaries of the park.

Crater Lake, at a depth of 1,943 feet, is the deepest lake in the United States and the seventh deepest lake in the world. The water in Crater Lake is very blue and this is due to the fact that it is exceptionally pure water. The average temperature is about 38 degrees but the lake has been known to warm up to as high as 56 degrees in the summertime.

There are two types of fish in the lake but neither are native. Rainbow Trout and Kokanee Salmon can both be fished in the lake. Crater Lake was stocked with fish in the late 1880's but these are the only two species that continue to survive in the lake. No fish are native to the lake.

While the park is open every day, all year, some roads and facilities may be closed in the winter due to the weather. http://www.nps.gov/crla/planyourvisit/campgrounds.htm

Stories of the eruption of Mount Mazama still circulate among the native peoples in the area. Although it does not seem the area was a home to any one native tribe, it was a camping area as people passed through it. The native people did not share the stories of the vividly blue Crater Lake with Europeans as it was considered a holy place for them. So it wasn't until 1853, that some miners came across it and started telling of the "Deep Blue Lake". In 1893, William Steele saw the lake for the first time. He loved the beauty of the lake so much, he was moved to begin what would be the seventeen year task of seeing Crater Lake become a National Park. Crater Lake became one of the first National Parks on May 22, 1902.
