The Teanaway, a land of geologic mystery

March 11, 2016

Last week, we revealed a new one-page geologic map and summary centered on the agency’s new Teanaway Community Forest and surrounding area. We told you about the kinds of rocks found in the area and some of the processes that formed them. Yet, for what we know, there are just as many intriguing questions that scientists with our Washington State Division of Geology and Earth Sciences are still wondering. In many ways, the geology of the Teanaway is still very much mystery.

Here are a few of our unanswered questions. If you have relevant research, let us know so we can add it to the State’s Geologic Library. If you’re looking for a research project, here are some ideas.

Teanaway Mystery #1 – Given that there are multiple fault lines in the area and numerous small earthquakes, we think that a large earthquake here may be possible. But what we don’t know is how large or how often such events have been in recent history. (Recent history is defined as the last 20,000 years in geologic terms, by the way).

Teanaway Mystery #2 – As an area with many steep slopes, it’s not surprising that we see evidence of landslides over millennia. But, how old are they, what triggered them, and what is it about the underlying geology that led the land to slide?

Teanaway Mystery #3 – The Eocene, a period 34 to 58 million years ago, was a time of dynamic geologic change. Giant volcanic and tectonic shifts were taking place. The Cascade Range had yet to be made. Rivers and swamps existed near present-day Cle Elum. Although we know that many of the changes were related to how the continent was shifting, we don’t exactly know why things changed the way that they did.

As the state’s repository for geologic information, our quest is to understand what lies beneath our state and its likely impact on us today. That’s an unending task when you consider what we don’t know – even for this one part of Washington. Yet, with talented professionals entering the field and quality education programs throughout Washington we’re confident that many of our mysteries will be revealed in the decades to come.

We hope these mysteries inspire you to ask your own questions. Find out more about:

  • Pursuing a geology career. You can study Washington geology in Bellingham, Cheney, Ellensburg, Pullman, Seattle, Tacoma, or Walla Walla as most of Washington’s 4-year schools offer a bachelors of arts and Science degree in general geology, seismology and geophysics, or geochemistry science. Almost half of these schools also offer post-graduate degrees.
  • The Teanaway Community Forest
  • The Geology and Earth Sciences Division
  • The geology of this region, the South Cascades and Columbia Basin provinces

One thing we know for sure is that we’re going to continue enjoying the forests’ mysterious rock formations, no matter how long it takes us to fully understand them.

Lessons remain vital five years after deadly Japan earthquake, tsunami

March 11, 2016

On March 11 five years ago, the earth reminded us of its destructive and unstoppable power when a magnitude 9 earthquake in northern Japan touched off a tsunami and caused tens of thousands of deaths and devastated much of the nation’s infrastructure.

Waves from the tsunami reached the coast of Washington and other western states, where they damaged California coastal communities and washed some of the estimated 1.5 million tons of tsunami debris onto our shores.

Not only is the anniversary a time to remember those lost in Japan, but it should also serve as a reminder that Washington needs to be prepared for a similar geologic hazard threat.

An earthquake fault with similar potential lies just off the coasts of Washington, Oregon and British Columbia. Geologists say it is not a matter of ‘if’ but ‘when’ the Cascadia fault off our coast unleashes another mega quake.

Damaging tsunamis have hit the Washington and Pacific Northwest coast in the past. These events are recorded in oral Native American history and in the geologic record.

 

To get a picture of what we may need to do in the recovery, DNR and other members of the Washington State Seismic Safety Committee produced the ‘Resilient Washington State’ report.

DNR’s Geology and Earth Resources Division, the state’s official geologic survey, is helping Washington communities identify how they are vulnerable to similar tsunami events and how they can craft innovative strategies for dealing with those threats.

Following the 2004 Indian Ocean earthquake and tsunami, the Tsunami Warning and Education Act of 2006 was put in place. The act allowed NOAA to formalize and expand the National Tsunami Hazard Mitigation Program, a partnership with Pacific states to protect the West Coast from tsunamis.

Hazards geologists with the Department of Natural Resources Division of Geology and Earth Resources, the National Center for Tsunami Research at NOAA’s Pacific Marine Environmental Laboratory, and scientists with the University of Washington model tsunami inundation in population centers both along the Washington coast and within the Puget Sound.

To do this complex math, the geologists use software (Clawpack), developed by the Applied Mathematics Department of UW or the MOST model, developed by NOAA.

A recently published inundation map for the city of Everett models how a tsunami would likely impact the Everett area. We also have dozens of publications for communities like Neah Bay, Tacoma, Anacortes and many others that would be hit by tsunamis.

DNR has charted evacuation routes for those in communities that might be impacted by tsunamis on our interactive geologic map. You can take those routes with you on your phone with this tsunami evacuation app.

To stay up to date on tsunamis, tune in to the Pacific Tsunami Warning Center.

A big thank you to volunteers with the Skagit County chapter of the Back Country Horsemen of Washington, who have been hard at work caring for trails in DNR’s Harry Osborne State Forest to manage drainage issues.

Using crushed rock, meshed fabric, and logs to drain water, volunteers have been working to manage drainage with the forest’s 40-mile trail system, popular for horseback riding.

Their work comes with the help of a roughly $18,000 Washington Recreation and Conservation Office grant, just for the chapter to use in Harry Osborne.

Join the effort
The chapter has had two work parties this year dedicated to trail drainage. Their next work party is:

9 a.m. to 3 p.m.
Saturday, March 12
Les Hilde Trailhead

Visit our event listing for more information. Watch our calendar for future work parties.

To read more about their efforts, visit this Skagit Valley Herald article.

Lasting stewardship
Volunteering on DNR-managed lands is about more than just giving back to the landscapes you love most, you’ll also gain new skills, meet new people, and spend valuable time in Washington’s great outdoors. For more information about volunteering with DNR, visit our website.

Defend your home from wildfire (Defienda su casa de incendios forestales)

Important tips to save your home from wildfire

Important tips to save your home from wildfire

Many people would like to live in a serene setting, away from the hustle and bustle of the city, but not completely isolated from familiar conveniences. The housing market is responding to these desires by building new neighborhoods in the countryside – and scores of new home buyers are settling in each year. Unfortunately, this trend is happening as signs point to a warmer climate with more intense and frequent wildfires ahead.

How can you – as just one member of a community in an outlying area – prepare for the threat of wildfires?

You can clear out the brush, tree limbs and other woody material from along driveways and other access roads to your property. This firebreak may stop, or at least slow, an oncoming wildfire.

Protect your home by lopping off those pesky low-lying limbs from trees and removing flammable material from the grounds around your house. To some, a green lawn looks out of place around a rural home site, but it may just save your house from the worst of a wildfire. If you’re remodeling or building a new home, consider installing a metal roof and using other fire-resistant materials where possible.

With the help of the Washington State Commission on Hispanic Affairs, DNR has created a flyer in English & Spanish that tells how to create a space around homes that helps defend from wildfires.

…Con la ayuda de La Comisión de Asuntos Hispanos del estado de Washington, el Departamento de Resources Naturales (DNR) ha creado un volante en español que describe visualmente cómo crear un espacio de seguridad alrededor de las casas para ayudar a defenderlas de incendios forestales.

Here are tips to make the area surrounding your home into a defensible space more likely to resist wildfire.

The Teanaway, a geologic story worth telling

March 5, 2016
Balanced or Exclamation Point Rock then&now

If these hills could talk they would tell tales of bubbling lava, ancient jungles roamed by coyote-sized horses, and a shoreline sculpted by great blocks of ice.

While all is quiet in the Teanaway now, the beauty that we enjoy today was formed by massive events that gave rise to one-of-a-kind geologic features. The fascinating landscape has a history of drawing people to its location, just a few miles east of Cle Elum.

Here the work of erosion has exposed impressive formations of resistant Roslyn Formation sandstone, remnants of 40 million year-old swamps and rivers that also left behind a coal field mined for more than 80 years.

Even older, a dark, blocky rock unique to this area, and accordingly named Teanaway Basalt, holds up the high ridges north and west of the forest. It was formed as continental plates moved and stretched creating cracks and fissures that basalt lava filled up from below. This process also formed small cavities in the basalt that later filled with silica-rich fluid. This fluid eventually crystallized and become rare Ellensburg Blue agates. It’s the only place in the world where the Ellensburg Blue agate exists.

So, we see that these hills, or at least their rocks, do talk. The Division of Geology and Earth Resources, a part of Washington state’s Department of Natural Resources, is helping people to interpret what these stones say.

A new one-page geologic map and summary centers in on the agency’s new Teanaway Community Forest and surrounding area. Print it and take it with you as you camp, hike, hunt, or climb across this special rockscape. Use it to spot signs of the area’s geology or explore points of interest in this scenic landscape. You’ll leave with a greater understanding and appreciation for how the surrounding mountains and valleys were formed.

The division intends to produce more such one-page summaries for other landscape destinations in the future. This one is available at www.dnr.wa.gov/Teanaway.

When you go, remember to bring your Discover Pass – its display on vehicles is required, as in other state lands.

Students leap to help assess seismic stability of schools

February 29, 2016

With their classmates huddled nearby around the laptop of DNR geologists, a group of students wait for the count of three to jump in the air together. Their landing generates a tiny earthquake picked up by sensors laid in the ground.

Around the computer, students yell “whoa!” as waves from the student-generated quake show up on the screen.

Last fall, DNR seismologists visited 21 schools in Thurston County for a project aimed at assessing how well these buildings would withstand earthquakes. (more…)

Fifteen years after Nisqually quake; efforts to map, predict damage stepped up

Earthquake centered under Anderson Island touched off increased attention in earthquake science and emergency preparedness.

It’s been a decade and a half since Washington felt its last damaging earthquake.

At 10:54 a.m. on Feb. 28, 2001 a magnitude 6.8 earthquake struck near Anderson Island. Known as the Nisqually Earthquake, the temblor shook the Pacific Northwest, with shaking being felt around Puget Sound, in Vancouver, B.C., Portland, Ore., and as far east as Montana. The Nisqually earthquake produced some $2 billion in damages and injured about 400 people.

Damage could have been much worse, according to reports prepared by DNR’s Division of Geology and Earth Resources. This quake stemmed from the Benioff zone, meaning it came from deep underground (more than 32 miles underground.) The depth of the epicenter meant much of its force was buffered by layers of earth.

But on the plus side, the Nisqually quake was responsible for a new set of preparedness measures and research into Washington’s tectonics. (more…)
