Details for: Crater Lake
The 8 x 10 km wide Crater Lake caldera, one of the most spectacular features of the Cascade Range, was formed about 6850 years ago during one of the world's largest Holocene eruptions. This eruption resulted in the collapse of ancestral Mount Mazama, a complex of overlapping stratovolcanoes and shield volcanoes. This view from the east shows Mount Scott, one of the pre-caldera stratovolcanoes, in the right foreground. A post-caldera cone, Wizard Island, rises above the far lake surface.
