Crater Lake National Park

Crater Lake National Park, located in Oregon, was created on May 22, 1902 by President Theodore Roosevelt. The lake is actually the crater of Mount Mazama which erupted about 7,700 years ago. The crater formed after the top of the volcano collapsed forming a caldera. The caldera then filled with water from ice, snow and rain. Crater Lake attracts visitors from all over the world. At a depth of 1,943 feet, it is the deepest lake in the United States, and the seventh deepest in the world. It's crystal-clear blue water is some of the clearest found anywhere in the world. The park is 183,225 acres in size and had over 423,551 visitors in 2011. The stamp, issued on September 5, 1934, shows a rendering of the lake with Wizard Island at its center.
