Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute will meet at 7:00 P.M., Tuesday, February 12 at the Wenatchee Valley Museum, 127 South Mission, Wenatchee.

Our speaker is Nick Zentner, the animated and gifted teacher/geologist from CWU. His topic:

Supervolcanoes in the Pacific Northwest

Why is there 30 feet of volcanic ash south of Vantage, Washington? 

For years, geologists thought the tephra must have come from a big eruption in the Cascades. New data from the ash bed confirms that a supervolcano in southern Idaho erupted 11.8 million years ago and sent ash to Washington and Nebraska simultaneously!

Check out Nick’s website,, with links to his lectures, his 2-Minutes Geology, Roadside Geology, and PBS videos. And now he has a podcast! “The Nick Zentner Geology Podcast.”

The program is free & open to the public.
