science ping. And last night I watched a show about "monster volcanoes" that go off every several hundred thousand years with enough force to cause massive plant and animal killing ice ages. And Yellowstone national park is one of them and the most active.

But didn't you know that the federal government is going to control all the volcanoes to stop global warming? (sarc)

Thanks for the ping. I have read about symptoms of a major impact off the southeast coast of Australia in historic time.
