The area encompassed by Crater Lake National Park is underlain by a variety of volcanic rocks that record more than , years of complex volcanism in this part of the Cascade volcanic arc. Early eruptions in this area built an imposing volcanic mountain known as Mount Mazama. Mount Mazama, constructed of overlap-.
