NASA Perplexed by Strange Geological Stripes Appearing in Russia
Near the Markha River in Arctic Siberia, the earth ripples in ways that scientists don’t fully understand. Earlier this week, NASA researchers posted a series of satellite images of the peculiar wrinkled landscape to the agency’s Earth Observatory website. Taken with the Landsat 8 satellite over several years, the photos show the land on both sides of the Markha River rippling with alternating dark and light stripes. The puzzling effect is visible in all four seasons, but it is most pronounced in winter, when white snow makes the contrasting pattern even more stark.

Dust From Asteroid That Ended Dinosaur Reign Closes Case on Impact Extinction Theory
Having dominated the planet’s surface for hundreds of millions of years, dinosaur diversity came to a dramatic conclusion some 66 million years ago at the hot end of an asteroid impact with what is today Mexico’s Yucatán Peninsula. It’s a theory so swollen with data that it’s hard to imagine any room for doubt remains that this is indeed what happened. Were it a cold case, it’d be rubber-stamped and filed under ‘Solved’ by now. But scientists are a nitpicky bunch, and a tiny gap in the chain of evidence linking signs of a global apocalypse with the scene of the crime has been begging to be closed. An international team of researchers collaborating on a study of material from the Yucatán Peninsula’s famous Chicxulub impact crater has finally matched the chemical signature of meteoritic dust within its rock with that of the geological boundary representing the dinosaur extinction event. It appears to be a clear sign that the thin blanket of dust deposited on Earth’s crust 66 million years ago originated from an impact event at this very spot.

Explore PacNW Geology with Nick Zentner
Nick Zentner, an awesome geology instructor at Central Washington Univ., has kept quite busy since Covid curtailed his in-person lectures and professional video productions with a series of home-made videos exploring a broad range of geologic topics. Each of his engaging “Nick from Home” series last Spring went in-depth for an hour or more into a plethora of topics he briefly covered in his earlier “Nick On The Rocks” and other short videos. This Fall he decided to explore and learn more about the exotic terranes of the Pacific NW in another series of engaging at-home videos. These “Nick at Home” videos are not exactly elaborate productions. They are generally about an hour long and livestreamed with a cell phone to his YouTube channel where the y are recorded as videos and available for others to discover. His ‘aw shucks’ demeanor has garnered fans from around the world, many of whom get online at all hours of their day or night just to watch Nick talk and digress about geology. Do you want to know about Baja BC, how whole blocks of the earth’s crust that originally formed in Mexico found their way to underlie a large part of the Pacific NW? Nick has videos about that. How about how giant mudflows roared down a flank of Mt. Rainier and now underlie much of Tacoma, Washington. Yep, Nick has videos about that too. Or maybe something about gold in the Pacific NW. Well, you get the idea. Nick has just completed 26 videos exploring the ‘Exotic Terranes of the Pacific NW”, one for each letter of our alphabet. These livestream presentations are not rehearsed, Nick just takes his experience from 30+ years of teaching geology to not only teach about the subject, but also to get you wanting to understand and interested in what he is presenting. If you haven’t discovered Nick you’ve got a treat in store. And if you have discovered him, he is always offering something more to whet your geologic appetite. Here’s Nick’s YouTube channel gateway link so you can explore the geologic wonder-world of Nick Zentner. We hope you enjoy it.
Ice Age Floods Museum in Lacrosse, WA
Work has begun on the Ice Age Floods Museum in Lacrosse. The accompanying photo shows that the rock from the existing rock houses has been removed and new foundations have been poured. The rock will then be set back in place and the structures will be similar to the house seen in the back which is the temporary home of the museum today. We will have four of these bunk houses which will be available to travelers. Once these are done, the work will begin on the rock gas station next to these which will be the final home of the museum. “Local businessman Clint Dobson is credited with building the unique collection of structures known as the LaCrosse rock houses and station between 1934 and 1936. The project included three houses, three cabins, and a service station with all buildings prominently featuring basalt stones collected from the surrounding fields. Dobson was not a master stone mason, rather, basalt stone was the most readily available material in the area during the Great Depression. “Local farm hands, workers, and railroad crews used the houses and cabins as rental units, while the station offered a service and repair shop. Although the structures have not been in use since the 1960s, amazingly all but one of the houses remain. Those remaining buildings, however, are in critical danger of collapse if they do not receive repairs to stabilize and secure the stone and structural elements. “Hope for rehabilitation increased when a local family gifted the property to LaCrosse Community Pride, which enjoys a strong track record of successful community development projects in town. Following the closure of the town’s only grocery store, LaCrosse Community Pride embarked on an effort to re-invent that site as an ongoing enterprise and community center. Today, the building houses a new grocery store, the local library, a community meeting space, and two rentable office spaces. The group also organized efforts to return a bank to the town when the local branch closed: they purchased the bank building, secured a new tenant to run the bank, and are currently working to find another tenant for the adjacent café. “The Washington Trust was proud to support LaCrosse Community Pride in rebuilding one of the stone cabins through a Valerie Sivinski Fund grant. Now they are fundraising for the rehabilitation of the remaining buildings and just last month were recommended to receive a state Heritage Capital Grant to realize their vision of creating a heritage museum and Ice Age floods center in the service station along with places for visitors to stay in the homes and bunkhouses.” From Washington Trust for Historic Preservation
IAFI Board Sets New Strategic Plan
Since June the IAFI Board of Directors have been working to revise and update the IAFI Strategic Business Plan that was created in 2006. A lot of that plan has been achieved since then, while some parts are still actively being addressed and other parts are no longer relevant. The newly revised plan that was officially adopted in our October 10 board meeting lays out goals, strategies and action plans for the next two years that address Membership Services, Trail Advocacy, Education and Outreach, Organization Leadership, Administration and Finance. Five committee teams (Education and Outreach, Technical Committee, Membership Services, Trail Advocacy, Administration and Finance) were charged with identifying specific goals, strategies and action plans, and “champions” were assigned to push the action plans forward and to report progress at our regular board meetings. The full 28-page 2020 Ice Age Floods Institute Strategic Plan is available online and we anticipate reporting regularly on our progress as we work to continue the IAFI Vision to be “the foremost provider of Ice Age floods scientific advice and marketing communications through member, partner and direct public collaborations“, and Mission to be “dedicated to promoting public awareness and education relating to the significance of the Ice Age floods“
Chapters Go Virtual for Meetings and Presentations
Covid-19 has sure put a stop to in-person meetings and presentations, but that’s no reason why chapter meetings and presentations can’t still reach out and be available to IAFI members. In fact, several IAFI chapters have been able to increase their outreach and attendance through the use of online ‘virtual’ meetings and presentations. And as an added bonus, the presentations can be easily recorded and made available online to those who weren’t able to attend the live online event. The Lower Columbia chapter has led the way with 4 monthly meeting presentations that have been recorded and later made available on their local GigaFlood website. These include Antarctic Glaciers by Dr. Scott Burns, The Lake Missoula Floods in NW Oregon and SW Washington by Rick Thompson, Global MegaFlood Science by Dr. Victor Baker, and 10 Ways the Lake Missoula Floods Still Affect Us Today by Rick Thompson. Of course Nick Zentner of the Ellensburg Chapter has long been producing and posting videos of his public lectures and his 2-Minute Geology and Nick on the Rocks series, as well as a large library of Covid-era explorations of local geology. The Cheney-Palouse Chapter and the Lake Lewis Chapter have also held their own online virtual meetings and presentations including a recent presentation of Ice Age Floodscapes of the Pacific NW by Bruce Bjornstad for the Lake Lewis Chapter. We hope that other chapters can soon follow suit and that recordings of these and other future events can be made available to our larger IAFI membership.
LaCrosse Heritage Museum and Ice Age Visitor Center Moving Forward!
With strong community support, in-kind pledges from local volunteers and businesses, recently awarded grants from the Port of Whitman and Whitman County, and a major state grant request in the hopper, the historic rock houses of LaCrosse are soon to get a major face-lift. Three years ago, LaCrosse Community Pride leaders and local businesses renovated one of the crumbling old rock bunkhouses, built during the Great Depression of boulders left behind by glacial floodwaters. That project showed the historic rock buildings could be saved and provided temporary quarters for displays of the Ice Age Floods Institute and the Whitman County Library, partners in the project. Next up? The old rock service station will be transformed into a Heritage Museum and Ice Age Visitor Center. The bunkhouses, two more of which will be renovated, will provide more room for exhibits, a business incubator and overnight lodging. Lloyd Stoess and the Palouse Falls chapter will share our remarkable geologic history. The National Park Service and its National Natural Landscape program leaders have been interested in helping, too. We’re planning to break ground on the project this fall. The LaCrosse Community Pride team thanks Lloyd Stoess and all of you, for steadfast support of this ambitious endeavor. This is a two-year project that will require many hands to complete. If you are interested in learning more or seeing how you can help, please contact Peggy Bryan (pegandpetebryan@yahoo.com) or Alex McGregor (alex@mcgregor.com). Submitted by Leslie Druffel UPDATE: On the state Heritage Capital projects, Alex McGregor reports that we ranked 12th out of 40 applicants and received all positive comments from the judges and that no other project prompted this kind of excitement and curiosity.
4th Badger Mtn Interpretive Sign Installed
Friends of Badger have completed installing the 4th interpretive sign about Lake Lewis Isles on Candy Mountain – one more to go, plus three more for Badger Mountain. Lake Lewis was a temporary lake that repeatedly formed during the Pleistocene Epoch as Ice Age flood waters (mostly from Glacial Lake Missoula) backed up behind a constriction at Wallula Gap. The Lake Lewis Isles name is given to several basalt hills south and west of Richland, Washington, whose crests stuck up above the maximum flood level (1,200 -1250 feet) of temporary Lake Lewis, making them islands. These temporary islands include Badger Mountain, Candy Mountain, Goose Hill, and Red Mountain. Only the top 380 feet of Badger Mountain poked out above Lake Lewis. Icebergs and other floating debris (such as mammoth carcasses) drifted into quieter waters and ran aground along the shorelines of these islands, leaving behind giant boulders of exotic rock types (erratics) from up to several hundred miles away. The scene of Lake Lewis, with its temporary Isles protruding out of the lake and occasional icebergs carrying erratics, can probably be best be imagined from one of the Badger Mountain or Candy Mountain trails, or along Interstate Highway I-182 as it passes through Goose Gap approximately 3 miles southwest of Richland. We encourage you to explore the trails and imagine the vistas of recurring temporary Lake Lewis. Our interpretive signs will help you peek into the distant past and the incredible Ice Age Floods story.
”Global Megaflood Science” Dr. Vic Baker
“Global Megaflood Science” – Dr. Victor R. Baker – Lower Columbia Chapter -Virtual Meeting Starting in the late 1960s, an accelerating pace of discovery has revealed that the last major de-glaciation of planet Earth involved a global pattern of huge outbursts of water from the margins of wasting continental ice sheets. Much of this water was delivered as relatively short-duration floods with peak flows comparable to those of ocean currents. The global inventory of these phenomena now includes about 4 dozen examples from Asia, Europe, North America, South America, and Iceland. Though there have been many advances in understanding the physical processes and geochronology of megaflooding, important controversies remain, including: the role of flooding on areas that are now under the oceans; the nature of subglacial megaflooding; and the details of the vast network of megaflood landscape features in Asia. Immense outburst floods likely induced very rapid, short-term effects on the global Earth environment. Recorded Thursday, July 16, 2020 at 7:00 PM
