THIS TRIP IS FULL!

The North Cascades Institute is offering a one day geo field trip to the Schreibers Meadow cinder cone on the south flank of Mount Baker. The trip is on Saturday, June 18, and is led by Dave Tucker, one of MBVRC’s directors. The trip includes bus transport from Sedro Woolley and a trip hand out.

Registration: http://ncascades.org/signup/programs/geology-cinder-cones-and-crater-lakes

The cinder cone is the best-preserved in the northern Cascades, a complete, isolated little hill containing to lakes in the unbreached, double crater. The hike to the cinder cone is 2 miles round trip, with little elevation gain until the end. Just up the trail from the parking lot we hike 1/4 mile cross country through the boggy huckleberry-covered Schreibers Meadows, then steeply up through the old growth for 100 feet or so to the forested rim of the cone. It is not for everyone- you will need to be able to get up and down the steep timbered slope through bushes. You will need sturdy shoes, good leather or heavy fabric gloves, trekking poles and sack lunch.

Displaying this website on a mobile device

I don’t have a smart phone. If you do, this website may not display well on yours. You can fix that. Bring up this page on your device, and scroll all the way to the bottom. There will be an option to ‘display full website’ or something to that effect. Tap that, and voila, the website will look like it is designed to on a desktop, with all the tabs. Much easier to find your way around. OK, so maybe I’m just a troglodyte [thanks to Spiro T. Agnew for popularizing that wonderful word back in the 1970s] and everyone knows how to do this. But I suspect some folks don’t because they have mentioned this to me. Give it a try.

Your semi-luddite friend.

Earthquake below Deming Glacier, Mount Baker

Map showing location of M 1.6 seismic event at Deming Glacier

Map showing location of M 1.6 seismic event at Deming Glacier

By D. Tucker 6-30-15

A 1.6 earthquake was detected Sunday June 28 at the Deming Glacier. Puget Sound Seismic Network reports it occurred at 12:19:49 PDT at a depth of 0.0 km. This is a steep icefall and collapsing ice may be the source of the signal.

It is probably only significant because it is the first seismic signal from Mount Baker since November 12, 2014.

Northwest Geology Field Trips website

Dear friends,

A reminder that I manage two geology web sites. You may have inadvertently signed up for the wrong one. This one, and the Northwest Geology Field Trips website. That blog is here: nwgeology.wordpress.com. I publish self-guided geology field trips there, and short primers on some basic aspects of geology. Also information about my upcoming book, Geology Underfoot in Western Washington (due in stores the end of April). Check it out! You subscribe to it in the same way you subscribe to the MBVRC blog.  Thanks, Dave Tucker

GUWW cover

To be released in May, 2015. The cover image shows an interpreted eruption at Mount Rainier, and lahars descending into lowland valleys. Art by Eric Knight.

A “people’s geology guide to western Washington” will be published in May. Geology Underfoot in Western Washington, written by Dave Tucker, one of MBVRC’s directors, will be published by Mountain Press Publishing (Missoula). The book details geology (and necessary background)  at 22 sites between the Columbia River and the British Columbia border, and from the Cascades to the Olympic coast. Each chapter describes a particular location. Some are close to Bellingham: the Kulshan caldera and Table Mountain at Artist Point, the Western Washington University Geology Museum and the giant fossil bird track found near Kendall, and Larrabee Park’s stunning ‘honeycomb’ weathering. Some sites are right next to the road, others require some hiking. There is a geology 101-style introduction, and many color photos, diagrams and maps. The book will be for sale at Village Books in Bellingham’s Fairhaven district, as well as bookstores all over the region.

An opportunity for citiizen volunteers to assist with USGS river and storm surge monitoring

From Eric E. Grossman, PhD, Research Geologist, U.S. Geological Survey

Hi,

As part of our USGS Coastal Habitats in Puget Sound Project and WWU Coastal Resilience Project, we actively measure river floods and storm surge/wave impacts. We have witnessed some extreme flooding, inundation and erosion the last few storms and need help.

Volunteers are requested to help:

1) measure river flow and its partitioning through delta distributaries using fancy Acoustic Doppler Current Profilers

2) sample for suspended and bed load sediment

3) map bedforms and changes in channel morphology/aggradation

4) measure maximum runup and inundation following floods/storms with RTK-GPS

5) Deploy instrument packages that continuously measure water levels (tides), waves, currents, suspended sediment flux and water temperature/salinity.

This work is ongoing with a big push during the winter months. If anyone is available periodically for full or half-day outings please contact Eric Grossman – USGS/WWU Geologist (831-234-4674 or 360-650-4697) and/or Christopher Curran – Hydrologist, USGS, 253-380-7409). If anyone is around during the Holidays and interested in exciting field days, please let us know.

Thanks and have fun and safe Holidays,

Baker eruption simulation, Dec 14, 2014

Simulated ash deposit thickness from alarge Mount Baker eruption, Dec 14, 2014. Thickness in mm. Click to enlarge.

A reminder that an animated eruption simulation is available on this website. A repeat of the last large Baker eruption today, with prevailing winds, would drop 3 cm of ash on Bellingham; the Lower Mainland would receive 1 cm to only 1 mm, depending on distance from the volcano. The effect on Bellingham would be serious, and even 1 cm in a big urban area could affect internal combustion engines. Airports would certainly be shut down. Click the ‘monitoring and webcams’ tab at the top of the page to go to the simulation, and learn more about the geologic basis for model. Or, go directly to the simulations page: https://mbvrc.wordpress.com/monitoring/todays-mount-baker-eruption-simulation-from-usgs/

Mount Baker earthquakes in November

Two small earthquakes have occurred near Mount Baker in November, the second and third detected in 2014. Magnitudes were 1.9 and 1.1. Though small, they were still among the largest earthquakes at Cascade volcanoes in the past month. They are not considered anything other than normal.

Locations: http://pnsn.org/volcanoes/mount-baker

1. On November 5th, there was an M 1.9 event just after midnight at or near the terminus of the Thunder Glacier, 4 km west of Mount Baker’s summit. Though small, this is still among the largest earthquakes recorded at the volcano in the past 9 years (see graph at the link above- scroll down there in the right margin’s list. Pacific Northwest Seismic Center’s report page: http://pnsn.org/event/60917886#overview Note the uncertainty in depth of this seismic event, 31.61 km vs. horizontal error, only 0.6 km. The waveforms are here: http://pnsn.org/event/60917886#waveforms  Note that the top two graphs are from the nearest seismic stations, MBW (2.8 km distant) and SHUK, near the Mount Baker ski area, 16.1 km distant.

2. On November 12th, an M 1.1 earthquake was centered beneath the right valley wall of Park Creek on the east flank, nearly 10 km from the summit. Pacific Northwest Seismic Center’s report page: http://pnsn.org/event/60914762#overview The event was reported at 4.5 km depth, but note the uncertainty in depth of this seismic event is less than the other, merely 15.87 km. The horizontal error is nearly 1 km. The waveforms are here: http://pnsn.org/event/60914762#waveforms  MBW (15.8 km distant) and SHUK, near the Mount Baker ski area, 12.6 km distant.

In contrast, only one small earthquake was reported in 2013 (and that was likely due to blasting), and one each in 2012 and 2011.

MOUNT BAKER ERUPTIVE HISTORY AND HAZARD PRESENTATION

Whatcom County Library System is sponsoring 3 Mount Baker talks.

“MOUNT BAKER ERUPTION HISTORY AND HAZARDS”

Deming Library, October 18, 4 PM.

Ferndale Library, October 21, 7 PM.

Everson Library, November 8, 3 PM.

ABOUT THE MOUNT BAKER ERUPTIVE HISTORY AND HAZARD PRESENTATION

The talk presents the volcanic history of Mount Baker: eruptions, collapses, and the hazards this active volcano poses. The state of monitoring at the volcano will be discussed. The likely volcanic future and the potential for impacts on Whatcom-Skagit communities will close out the presentation.

Only 40,000 years old, the Mount Baker cone is about the same age as Mount St. Helens. Very little was known of its volcanic history until extensive geologic mapping by USGS geologists Wes Hildreth and Kevin Scott began in the mid 1990s. We now know that Mount Baker is but the youngest in a series of volcanoes in the immediate area extending back over 1,000,000 years. Other volcanoes in the Baker group include: two calderas that each erupted roughly 200 times as much ash as Mount Saint Helens did in 1980; a subglacial cone; and a number of once-sizable stratovolcanoes, most now eroded to nubs. Collapse of the volcano’s southwestern slope sent a large mudflow, or lahar, down the Middle Fork Nooksack River into the lowlands of Whatcom County and possibly as far as the Fraser River. Field studies continue to describe the post-glacial eruptive history. The newest, soon-to-be published research has revealed the patterns of ash deposits erupted from Mount Baker.

The presentations are given either by Dave Tucker , a research associate in the geology department at Western Washington University, or Doug McKeever, geology professor at Whatcom Community College. Both are board members of MBVRC, and have carried out considerable field work on the volcano.
