It’s not what you thought it was. If you’re into plate tectonic and the wonders of geology, you’ll want to watch this, it’s insightful and will rearrange your thinking in wonderful ways. Talk about folds within folds.
I think Nick Zenter is a great teacher, and having spent a little time in the state of Washington I was able to relate to his talks and been a fan of his for years.
I’ve always wished someone like him would show up to discuss the Rockies.
Now it’s nice to him stepping up, although in these talks he’s doing a Rocky Mtn overview, but that’s close enough, especially since he’s introducing us non-geologists a radical, but fact driven, (fairly) new theory about the history of Rocky Mountain formation and it’s a trip.
He’s synthesizing and reporting on what may turn out to be one of the biggest upheavals in geologic understanding since the Plate Tectonics revolution took hold. Well at least for those of us who remember learning about the then new findings suggestioning that the Juan de Fuca Plate diving under California and then rebounding and pushing up the Rockies.
Earth is some 4 and a half billion years old. Moving at an average speed roughly equal to how fast your finger nails grow, it only takes a few hundred million years for tectonic plates to circumnavigate the globe.
Now keep in mind that floating crust is on “mushy” layers mantle. Viscous stuff plowing through other viscous stuff, leaving tracks and remnants within the global, and scientists keep getting better at unraveling the information.

CWU’s Nick Zentner presents a new lecture - the 29th talk in his ongoing ‘Downtown Geology Lecture Series’. Recorded at Morgan Auditorium on March 30, 2023 in Ellensburg, Washington, USA.

. . . But now scientists have further insight into the solution of this mystery. Jones and his team of researchers have proposed a new model of the mountains’ creation and published their results in the February edition of the journal Geosphere. Not only could their research explain the origin of the Rockies, it could also elucidate other geological phenomena: why a swath of gold, silver and other precious metal deposits stretches across Colorado, and why a marine basin deepened in the states of Colorado and Wyoming just before the Rockies rose. The sediments of this marine basin are the Pierre Shale, a layer of dark-gray shale lying along the Front Range of Colorado. “Pierre Shale has this nasty tendency to bow up people’s basements,” Jones said. “Why more than a mile of this stuff was dumped into this area has been puzzling.”
Previously scientists believed that the oceanic plate subducting . . .
