Crater Lake National Park , located in southern Oregon, is famous for its deep blue color and spectacular scenery. The lake itself sits atop a 6 mile wide caldera that was formed some 7,000 years ago by the eruption and collapse of Mt. Mazama. The lake is rimmed with beautiful forests of fir, hemlock, and pine. Crater Lake (1,932 feet) is America’s deepest lake, and second deepest in North America. Crater Lake National Park averages over 533 inches of snow in the winter. In 1950, the park received 903 inches of snow!
