Crater Lake National Park
Crater Lake in the Summer - Travel Oregon
7,700 years ago, the almost 12,000 feet (4000 m) high volcano Mt. Mazama erupted in an enormous explosion leaving nothing but a deep crater. Over hundreds of years, the crater filled with rain water and melted snow. At nearly 1,943 feet (600 m), it is the deepest lake in the U.S. A 33-mile (53 km) drive around the rim offers glimpses of the intensely blue-colored water which is created by the clarity and its depth. From July to September the Park Service offers boat tours. Outdoor enthusiasts find a large variety of summer hiking trails or winter sport possibilities in this outstanding national park.
