I traced backed on the earth's Timeline, the last time Ison approached was during this Period.....The magma chambers thought to underlie the Yellowstone hotspot also provide the park with one of its enduring symbols, its geysers, as the water is heated up by the hot magma that flows underneath the ground.

Some researchers have predicted that the supervolcano will blow its top again, an event that would cover up to half the country in ash up to 3 feet (1 meter) deep, one study predicts. The volcano only seems to go off about once every 600,000 years, though whether it ever will happen again isn't known for sure. Recently though, tremors have been recorded in the Yellowstone area.

It's utterly amazing! Ison was discovered little over a year ago. Supposed first trip through solar system. Now at zero hour they say "oh yeah it's been here before, about half a million years ago. Any other last minute tidbits, "oh one other thing, don't look up-DUCK" God Bless!
