About

Mt. Mazama erupted ~7,700 years ago in one of the largest volcanic events of the Holocene — ejecting ~50 km³ of magma in days. The summit collapsed into the emptied chamber, leaving an 8 km caldera that filled with rain and snowmelt over the next few centuries. No streams flow in or out; the water is unusually pure and famously blue.
