Well, it's weeks later, and I'm not up in the far northlands of Southcentral AK anymore (but instead am in the snowy middle-lands of the West), but indeed, the sun did come out the day after I took the ice and snow photos of my last post, and the trees, especially the deciduous trees, were covered with inch-plus-thick rime ice.
There were birds hanging out, in the birch trees
It's been icy cold in the far northlands, with temperatures hovering not too far above zero for several days. The snow isn't really all that deep, only 8 inches in the back yard, but it's covering everything and hanging fairly heavy on the trees.
Snow on black spruce.
Looking upward, we can see ice crystals frozen on to the needles.
It was about 3°F when I was out taking these
This is a great video from WSDOT visualizing all of the geotechnical instrumentation and survey monitoring being done in Downtown Seattle above the Bertha TBM for the Alaska Way Viaduct Replacement project. Soldata is the company WSDOT hired to manage the monitoring. I heard a great presentation by a Soldata representative and a member of the Seattle Tunnel Partners in charge of the instrumentation and monitoring from the contractor's side several years ago at an AEG conference. You can read [...]
I recently came across this fine cartoon in a short lived magazine. Started in 1907 and published by the AYP Publishing Co, The Seattle Spirit Magazine: A Seattle Publication for Seattle People was created to promote Seattle and the Alaska Yukon Pacific Exposition. It was filled with bad poetry, songs, and jokes; photographs of the … Continue reading Annexing
The Alaska DNR is requesting public comments on its mining regulations for establishing and maintaining mining claims – 11 AAC Chapter 86. These regulations (as well as related regulations at 11 AAC 82 and 11 AAC 88) establish or address many of the requirements for locating claims on state lands, performing assessment work, paying rent, filing production … Continue

Here’s the February edition of my paper recommendations. This time we have: Paleoseismology in Germany and Nepal (the latter with a focus on charcoal dating techniques), Tsunamis in Greece, Portugal, Israel and Alaska, Turbidites in Portugal, New insights into the geodynamics of Iran and Mozambique, Rupture jumps on strike‐slip faults, and A MATLAB tool for seismic hazard calculations. Enjoy! Grützner, C., Fischer, P., & Reicherter, K., 2016. Holocene surface ruptures of the [...]
These are the big subduction zones of the world. Here, an M7 is like a 4 to us. A clean, gently curving zone probably means a 9+ every 800 years or so, just like Japan. This is at a weird corner, with the upper zone very curved. Thus, that lower zone could probably get a 9.2 or 9.3 (two to three times longer than a 9), but the upper zone is probably limited to 8's. The zone
The Frozen North is known as a standout amongst the most plentiful ranges with salmon, and is perfect for angling trips. This is a direct result of great tides along the West Coast and the spout of sea streams that make a situation perfect for the rearing of a large number of baitfish. It is […]

In the early 1900s, before Alaska was part of the United States, geologists roamed this northern territory on foot and horseback, noting its features and terrain on hand-drawn maps. Nearly 100 years later in 1996, U.S. Geological Survey (USGS) research geologist Frederic Wilson and a dozen colleagues undertook the task of using some of the information contained in these field notes, sketches and maps, along with many other sources of data, to create the first fully digitalized geological map of [...]
In October 2015 the 72 million cubic metre Tyndall Glacier landslide in Alaska generated a significant tsunami that swept down the Taan
So, in just one (two-part) blog post, I propose to keep you from falling into a crazy cult, or posting one of those crazy videos on YouTube about chemtrails or the Moon landing hoax. Beware though, if you think what I’m saying is silly, then you’re at high risk already. It’s more than just the politicians in Alaska, that tell people with a straight face, that climate change is a
Climate modeling is hard. But perhaps more daunting is work to make the models more accurate. From deep-sea expeditions to high-altitude flights, scientists can go almost anywhere, gather data and[...]

We are closing in on a week of intense focus and excitement for GEOTRACES and for the United States around the Arctic. President Obama became the first sitting president to visit Alaska, the US Coast Guard Cutter Healy with US GEOTRACES scientists completed the first unaccompanied US surface vessel transit to the North Pole, and the first group ever to collect trace metals at the North Pole! You might assume these three items are unrelated, but they are in fact tightly
Houston, We Have Geology!Occasionally, I post various items that are not exotic or from faraway places. I'll be leaving for Alaska soon to run a wilderness river (the Tatshenshini) and so look for a post from that trip soon. In the meantime, here are a few odds and endsI just loved the above-the-fold headline in this mornings Arizona Daily Sun! Geology plays a prominent role in the upcoming New Horizons mission to Pluto. As you can imagine, Flagstaff has more than a passing [...]
"The journey of a thousand miles begins with one step" - Lao Tzu from the Tao Te ChingAnd that step would be to Boeing Field in South Seattle where we boarded our jet. The date was June 10 with a scheduled departure of 9:30 AM. We landed in Osaka Japan on June 11 at 2:30 PM but the flight was not 29 hours long - we crossed the International Date Line and jumped ahead a day.As this is a Private Jet journey, the security check was a little different from the regular and mundane. Our bus drove [...]
Guest Blogger: Audrey Steiner-Malumphy In 2011, Dr. Wiles and his advisees Lauren Vargo and Jennifer Horton cored dozens of trees from Tree Mountain in Alaska’s Glacier Bay National Park and Preserve. Muir Glacier is located northwest of this mountain, named after the esteemed naturalist and preservationist John Muir. Muir first traveled to the area in
Guest bloggers: Kaitlin Starr and Maddie Happ During the summer of 2014, the Columbia Bay team (Dr.Wiles, Nick Wiesenberg, Kaitlin Starr and Jesse Wiles) cored numerous trees near the town of Girdwood, Alaska. The collection is primarily made up of cores taken from living Mountain Hemlock trees from the surrounding forrest. In addition
From climate.NOAA.gov today: This temperature map of Alaska shows the unusual warmth on May 23, 2015, at 2 p.m. local time in Fairbanks. Based on NOAA’s Real-time Mesoscale Analysis data, it shows air temperatures at 2 meters (6.6 feet) above the ground. Temperatures below 45° are shades of blue, and temperatures above 45° are shades of orange and red. The warmest temperatures are located inland—away from the moderating influence of
Last week I was delighted to welcome fellow academics, friends and collaborators from Potsdam Universty, Ghent University, Durham University and The Geological Survey of Belgium to join me for a symposium on subduction zone palaeoseismology. The day-long meeting was an opportunity to present and discuss the different approaches that we use when studying past earthquakes, tsunamis and subduction zone behaviour. Coinciding with Dr Daniel Melnick's Distinguished International Visit, the Pan [...]
