Before It’s News – Red Alert: Yellowstone Supervolcano Getting Ready To Blow Full (Photo & Video)
“ The Yellowstone volcano has had three super eruptions – which produce more than 240 cubic miles of ash’ in the past.
One was 2.1 million years ago, another 1.3 million years ago and a third 640,000 years ago.
Ash from these eruptions has been found across the US on the east and west coasts.
The last volcanic activity at Yellowstone was 70,000 years ago which produced a lava flow in the south of the park.”

Note – to visit Yellowstone besides a volcano gas-mask and giant-size can of bear spray be sure to pack DOG LEASH if you plan on walking your dog next to boiling-hot springs there!

Series of Idaho earthquakes puzzling to scientists
“The latest earthquake swarm in central Idaho could help scientists better understand quake belts extending from Yellowstone National Park.”
“. . . The park is well-known as a geologic hotspot, sitting atop magma. But scientists said that doesn’t explain the earthquake swarms in Idaho.
“ It clearly is somehow related ,” Stickney said. “I’m not blaming the belts on Yellowstone, but the fact that they extend into and out of Yellowstone is not a coincidence. ” . . . “

Challis, Idaho which has so many quakes lately is full of old volcanoes!
“…The Challis Volcanic Group covers approximately 25,000 square kilometers in Idaho , making it the largest of the Eocene volcanic fields (Figure 2). The Eocene geologic setting of the Challis volcanics is commonly accepted as an extensional basin related to the subduction of the oceanic Farallon Plate beneath the continental North American Plate. Prior to Eocene time, before ~60 Ma, the convergence rate of the Farallon and North American Plates was very fast.”
Fun Fact:The caldron under Yellowstone started out to the right, under Idaho and moved left.
“The Yellowstone hot spot first appears about 17 million years ago with rhyolite eruptions – on the Owyhee Plateau of southeast Oregon and northern Nevada. The hot spot slowly migrates across southern Idaho to its present-day position at Yellowstone National Park.” Idaho history
