over Wizard Island
Lake is Oregons only National Park and part of the Cascade Range.
About 7000 years ago an ancient volcano called Mt. Mazama erupted
and lost it's entire top. Crater Lake was created when the volcano
collapsed. It is almost 2000 ft. deep. This is the reason for
the deep blue color of the water. Only the deep blue components
of the light get scattered back to the surface.
