A self-guided geology field trip to the second part of the Fidalgo ophiolite (oceanic crust section) is posted here. This field trip visits intrusive and sedimentary rocks on Fidalgo Island, including Mount Erie. This is the second installment in the ophiolite series, which started at the chunk of the mantle at Washington Park.

The April 12th guided geology field trip sponsored by Mount Baker Volcano Research Center will visit some of these rocks. Registration information is on the MBVRC website. If you have been waffling, time to be decisive- the trip is nearly full!

Mount Baker Volcano Research Center is offering gift certificates for geology field trips.  These make great gifts for your geophile friends and relatives. The cost  is $75 (the usual cost of a one day guided trip, including van transport) and can be applied to any field trip offered by MBVRC. This year there are plans to offer  trips to lowland sites in Northwest Washington in the late winter/early spring. In the summer, trips will go to locations around Mount Baker , and a multi-day trip to Mount St. Helens is in the early planning stages.

To purchase a gift certificate, send an email or letter to MBVRC. Include  the name of the person the certificate is for, as well as your mailing address. You may send payment via check payable to ‘MBVRC’ to  708 13th St, Bellingham, or use the MBVRC PayPal account – the account code is this email address:

You will receive a nicely printed gift certificate in the mail. Field trip fees beyond expenses go to the MBVRC research and education fund. To see brief descriptions of some  past geology field trips, scroll down here: http://mbvrc.wordpress.com/field-trips/

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.

Guided geology field trip by Dave Tucker: Baker River trail June 8th

Dear friends,

An alluvial fan is perfectly exposed in cross section along the Baker River trail.

An alluvial fan is perfectly exposed in cross-section along the Baker River trail.

Mount Baker Volcano Research Center is offering a field trip up the Baker River on June 8th. It is a fundraiser for the non-profit, and I’ll be leading it, along with Doug McKeever (Whatcom Community College) and Sue Madsen (Skagit Fisheries Enhancement).

Highlights include:

  • Shuksan greenschist (metamorphosed subducted seafloor basalt) which is the local bedrock;
  • new salmon restoration facilities;
  • an active alluvial fan;
  • river erosion and deposition;
  • a great variety of rocks in river bars;
  • rock slides;
  • a fantastic ‘faerie forest’ of lichen-draped maples.
  • If the weather be good- fabulous views into the heart of the North Cascades.

Cost is $75, includes van transport and a trip guide.

For info and registration, go to:

100 years of change on Mount Baker featured in Nov. 5th Bellingham Herald

Bellingham Herald Nov 5, 2012. Click to enlarge

Read the Bellingham Herald article (front page, above the fold in the ‘hard copy’) about the two Mount Baker photos taken 100 years apart. The 1912 photo was taken by E.D. Welsh, the 2012 photo by John Scurlock.

The commemorative posters are for sale by MBVRC as  a fundraiser for the research program.

100 years of glacial change at Mount Baker; fundraiser poster for sale.

The 1912 Welsh photo at top, and the 2012 Scurlock re-created photo below. Click to enlarge.

Mount Baker Volcano Research Center is selling 20 x 30 ” posters showing a fantastic 1912 photo of the entire south side of Mount Baker, and the re-created photograph taken by John Scurlock 100 years later. The photos were taken from the summit of Loomis Mountain, south of the volcano and show much detail. Glacial recession is remarkable. Hop on over to the MBVRC website to see the poster, see some details about changes that 100 years have wrought, and learn how to order one. PLEASE PASS THIS POST TO OTHERS to help raise funds for a good cause- the MBVRC research and scholarship fund.

Virtual geology field trip: Cougar Divide

Acres of flowers and meadows on the crest of Cougar Divide. Did I say I like this hike? The snow fingers mark the Dobbs Creek headwaters, site of many dikes. Copyright Dave Tucker.

I have broken out of my writing doldrums and written a self-guided geology field trip to Cougar Divide on the north flank of Mount Baker. Figure I better provide people with a summertime hike before it is too late! This hike is mostly volcanic geology that long predates Mount Baker. In fact, the oldest dated rock in the Mount Baker volcanic field is found on the ridge crest. That alone makes this beautiful hike significant.
