Montana teacher discusses Yellowstone supervolcano on History Channel

Craig Beals talks to his honors chemistry class Friday morning at Billings Senior High School.

In the classroom, Billings Senior High science teacher Craig Beals knows how to get his students’ attention. Things that go boom are always popular, and you really can’t go wrong with fire. This Monday, Beals will see if he can capture the interest of nationwide television viewers with a show featuring some of those same attractants, only on a much bigger scale. The History Channel show, “Secret Earth: Yellowstone Supervolcano,” will air at 8 p.m. in Montana. Continue Reading →

Busy year for Yellowstone supervolcano rumors

Steam rises from Excelsior Geyser Crater and Grand Prismatic Spring in Yellowstone National Park.

Have you heard about what's happening with the Yellowstone supervolcano? The biggest earthquake in more than 30 years hit Yellowstone National Park in March. Bison were seen this winter pushing outside the park's boundaries. Extremely high levels of helium are rushing out of hot springs and fumaroles. Seismic detection gear has gone haywire. The roads are melting! All of this can only mean one thing: an eruption of the Yellowstone supervolcano is imminent, right? Continue Reading →

A new technique for dating rocks produced in volcanic eruptions indicates that the Yellowstone supervolcano was more active than previously thought, but also bit less super. Researchers have just published the findings of a study that suggests a Yellowstone supervolcano eruption believed to have happened 2 million years ago was in fact two separate eruptions separated by at least 6,000 years. The discovery could require geologists studying the Yellowstone supervolcano and other similar sites to recalibrate their geologic clocks a bit, while also offering a better idea of what the future holds for the still-active region around Yellowstone National Park.
