- | The smoking gun for a cometary airburst creating massive wildfires and instantly melting a great deal of glacial ice (to shut down the thermohaline current) was found with iridium and platinum in ice core samples. A tentative crater has been identified in Greenland beneath the Hiawatha Crater. | + | The smoking gun for a cometary airburst or impact creating massive wildfires and instantly melting a great deal of glacial ice (to shut down the thermohaline current) was found with iridium and platinum in ice core samples.

- | A large magma chamber in eastern California near Mammoth Mountain blows in a VEI 7 eruption. The area still hosts hot springs and a geothermal plant, but the magma is gone from the pool. The crater filled with water at some point and formed a lake that drained roughly 100,000 years ago. Ash from the eruption likely covered much of the western United States. | + | A large magma chamber in eastern California near Mammoth Mountain blows in a VEI 7 eruption.
