File:On Government Trail looking across to Wizard Island (3679412273).jpg

Image Description: "A few days spent on the rim, on the trail, or in a launch upon the lake will give glimpses of world building features and nature history. At no point is there a beach. The steep walls descend and plunge into the water.

When Mt. Mazama collapsed leaving clean cut the edges which today are Crater Lake’s surrounding cliffs, there was instantly a surging back. The crumbling lavas were forced again up the huge chimney.

But not all the way. The vent became jammed. In three spots only did the fires emerge again. The small volcanoes formed in the hollow.

But these in turn soon choked and cooled. During succeeding ages springs poured their waters into the vast cavity, and Crater Lake was born. Its rising waters covered two of the small volcanic cones. The third still emerges. It is called Wizard Island."
