Paul Santi, Mines geology professor, is quoted in this article that was written after a Pennsylvania woman is believed to have fallen to her death in a sinkhole.

Sinkholes are fairly common, due to collapsed caves, old mines or dissolving material, but the circumstances in South Dakota stand out, said Paul Santi, a professor of geological engineering at the Colorado School of Mines.

The study authors coined the term “snow deluge” for one-in-20-year heavy snowfalls, when it’s cold and wet enough to maintain a deep snowpack through April 1. But even among these rare snow deluges, last year’s stood out as the snowiest, edging out ....

Three university petroleum engineering instructors who reviewed the regulators’ order ahead of Associated Press interviews pointed out the testing, which federal guidelines call for doing at least once every five years. “That timing is definitely ....

“A U.S. embargo on Russian oil is very politically attractive right now,″ said Morgan Bazilian, director of the Payne Institute at the Colorado School of Mines.

Through those messages, he’s not just speaking to NATO leaders, but directly to the citizens who may put pressure on them to do more, says Kenneth Osgood, professor of history at the Colorado School of Mines and an expert on propaganda and ....

“They seem to recognize that this is a war of images as much as a ground war,” said Kenneth Osgood, a professor of history and an expert on propaganda and intelligence at the Colorado School of Mines. “Because without support, as a military reality ....

Such fires can be ignited by lightning, humans and even spontaneously at temperatures as low as 86 degrees Fahrenheit (30 degrees Celsius), said Jurgen Brune, a Colorado School of Mines engineering professor.

“Simply knowing the existence of a mineral deposit that’s attractive geologically does not guarantee commercial viability,” said professor Rod Eggert, deputy director of the Critical Materials Institute at the Colorado School of Mines.

The potential shift back to producing rare earths shows how these mining projects evolve over time in response to the market, said professor Rod Eggert, deputy director of the Critical Materials Institute at the Colorado School of Mines.
