Scope and Contents Lalo Rock on the rim of Crater Lake looms above the nation's deepest lake in the background to the left of Wizard Island in this view from Discovery Point on the west side of the natural phenomenon. Encompassed in Oregon's only national park, Crater Lake was formed eons ago when the peak of 12,000 - foot Mt. Mazama collapsed during volcanic eruption. Wizard Island is an inactive volcanic cone in the 20 - square - mile, cliff - rimmed crater. Crater Lake National Park is on the crest of the...

Perched precariously on the rim of an ancient cauldron, a camera fan gets his picture of Crater Lake and Mt. 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).

Crater Lake was formed eons age when the peak of 12,000-foot Mt. Mazama collapsed during a volcanic eruption. Viewed here from Rim Village on the southwestern side of the lake, Wizard Island is an inactive volcanic cone in the 20-square-mile, cliff-rimmed crater which contains the deepest lake in the United States.

From near Crater Lake Lodge, Wizard Island and the lake like this, set in the cauldron of an ancient volcano, Mt. Mazama. Crater Lake, in Oregon's southern Cascade Mountains is one of the wonders of the world, 2000 feet deep, six miles wide and covering 20 square miles, formed when Mt. 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...
