Cascades Volcano Presentation in Bellingham, October 29

John Ewert

Dr. John Ewert

Guest speaker: John Ewert, Scientist-in-charge- of the Cascade Volcano Observatory, US Geological Survey, Vancouver, WA.

Whatcom Museum, October 29. Doors at 6:30, presentation at 7. Free, but please consider a $3 donation to the museum at the door.

The talk, sponsored by the Mount Baker Volcano Research Center, will focus on the current status of volcano monitoring and research throughout the Cascades. At CVO John oversees all research on the Cascade volcanos, and is  an authority on volcano monitoring. He has worked all over the world.

“We have a lot of volcanoes in the United States — 170 of them. … And since 1980 there have been something like 100 eruptions from 35 or so of them. So, volcanically, we’re pretty busy,” he said. “And in the Cascades we have 13 large volcanoes and a lot of smaller ones…you just never know when these volcanoes are going to switch on and move toward eruption.”

“And once you start getting earthquakes or see something happening at the surface, you’re already behind the curve if you haven’t been watching to see what is normal and what the baseline is,” Ewert said. “So if you’re coming to the game late, you never know how long the fuse is.”

A number of presentations about Mount Baker eruption history and hazards will be presented by MBVRC.

Kendall Elementary School, October 25.

La Connor Museum, November 2

Bellingham, Bloedel Donovan Park, November 18.

Guided field trip to Bellingham downtown geology- new date is July 9.

By Dave Tucker   June 1, 2011

Downtown Bellingham's lonely bedrock exposure

This building features igneous, sedimentary and metamorphic rocks, all within touching distance of each other. Click to enlarge.

I will lead a guided field trip to see building stones and the only surviving approachable bedrock outcrop in downtown Bellingham. The walking field trip is open to subscribers of this website, and is oriented toward people without an academic geology background. However, even a geologist may be surprised at the variety of rocks we will see. I will talk about the origins of these building stones, and the geologic stories they record.

Saturday, July 9, 2-4 PM

Cost is $30/person

On this two hour walking trip, we will see a wide variety of rocks: igneous, metamorphic and sedimentary, from many parts of North America and the world. Highlights include: fossiliferous Indiana limestone, the same rock used to face the Empire State Building; exotic stones used in sculptures; seismic hazards in Bellingham; several urbanites and how to tell them from natural stone, and much more. A printed tour guide will be provided.

The trip is limited to the first 20 paid participants. If there is sufficient interest, a second trip can be arranged. I have guided a version of this trip for WWU’s Academy for Lifelong Learning. Based on that experience, this trip will fill quickly, so do not delay.

335 million year old marine crinoid fossils, right downtown!

How to register:

Notify me of your intention to attend via email at

I will provide you with a mailing address for a check. The first 20 paid participants will be accepted onto the trip. A portion of proceeds will be donated to Mount Baker Volcano Research Center.
