Scott (background) in Crater Lake National Park, 56 miles north of Klamath Falls in Oregon. The seemingly small lava formation at left center is the Phantom Ship, a rock-hard wall which at times appears to be moving through the placid waters of the lake.

Oregon's Crater Lake National Park provides visitors with one of the world's most spectacular views. This unbelievably blue lake, six miles from shore to shore line, is set in the crater of the extinct volcano, Mt. Mazama, which collapsed ages ago. Later volcanic action built Wizard Island. A paved highway leads from Crater Lake Lodge (lower right) around the lake. (Oregon State Highway Department Photo 6639).

Scope and Contents A volcano within a volcano, Wizards Island is a frequently photographed featured of Crater Lake in Oregon's only national park.

Mazama, more than 12,000 feet high, was destroyed by volcanic action ab out 5,000 years ago. (Oregon State Highway Department Photo 5308).

Scope and Contents Crater Lake was formed ages ago when Mt. Mazama literally blew its top and collapsed into its own crater some six miles across. Later volcanic action formed Wizard Island (center), which has its own small crater. Eventually, volcanic action ceased and the crater filled to its present level where evaporation and seepage balance with annual rainfall. Because of the pureness of the water and the altitude, 6,200 feet, the lake has an exceptionally deep blue color. Hillman Peak (left) is the...
