The great Crater Lake in Oregon was once a stratovolcano named Mount Mazama. Mount Mazama had a very catastrophic pyroclastic eruption that produce about 12 cubic miles of magma. The Mount Mazama volcano has been recorded as one of the largest volcano eruption that has taken place in the last 10,000 years. The Mount Mazama volcano was one of the major volcanoes at the Cascade Range. The range of Mount Mazama’s summit was roughly between 11,000 and 12,000 prior to its climatic eruption. The climatic eruption took place in two stages. The first stage took place at a solitary vent that caused a Plinian eruption. There was so much magma that erupted that the vent widened and the eruption collapsed creating pyroclastic flows that deposited welded
