Planet Jackson Hole: Yellowstone supervolcano eruption would ELAWKI

Experts say a supervolcanic event in Yellowstone would be at least 50 times as powerful as the Krakatoa blast and 2,000 times the size of the 1980 Mount St. Helen’s eruption. In short, surrounding communities like West Yellowstone, Moran, and Cody would be Pompeii – buried in more than 240 cubic miles of pumice and ash. They would be the lucky ones.

Scientists are learning that the Yellowstone supervolcano is about two and half times as large as once believed and its eruption would "end life as we know it."
Not only was there a sudden rise in the elevation of the ground, and development of new cracks, but a gas called Helium-4, a very rare type of Helium, has begun coming out of the surface. It is the presence of this gas that has scientists quite concerned. If the Yellowstone Super Volcano were to erupt, it would be 2,000 times bigger than the eruption of Mount St. Helens in the 1980′s. Everything within 500 miles would be dead or destroyed within minutes, 2/3rds of the entire United States would be covered in volcanic ash and the climate of the entire planet would cool within a month. On top of that, just this past week, the largest earthquake in the US took place just a few miles from Yellowstone proving hot magma is on the move. Helium isotope ratios (³He/4He) in Lassen Park and Yellowstone Park volcanic gases show large ³He enrichments relative to atmospheric and crustal helium indicating the presence of a dominant mantle-helium component. Naysayers beware, the evidence is stacking up. if you’re waiting for an mass-media announcement….it has now happened and wont get any more direct. [Preppers World USA]

Rob Kailey's post in Montana's A Chicken Is Not Pillage elicited a flashback.

I recall this from the hang glider launch on Mt. Sentinel:

The wind was dead all day and we passed the time kicking the hacky sack.

Late in the afternoon a massive cloud filled the western horizon so everybody but me, the driver that day, ran their gliders into a scant breeze to beat the weather.

By the time I got off the mountain and back to the LZ, the golf course, the sky was so dark the street lights were coming on.

Not having thought to turn on a radio, I was totally freaked when ash began falling from the sky. Only after running back to the pickup and turning on the news did I learn.

The next week in Missoula was spent inside with the windows duct-taped shut and not being able to see the sun or even across the street, for that matter. An emergency executive diktat from the governor shut the town down.

Stores ran low on essentials and going outside meant stinging eyes and sand gritting in your teeth.

After a week of cabin fever, I took the top off my '65 Land Cruiser, drove into the Rattlesnake, and saw my first black bear in Montana.

Thanks, Rob.
