SUMMARY:Bill Burgel - Geology in the Growth of the Railroad Industry
DESCRIPTION:Bill Burgel will give a presentation on the Synergy between the development of the science of Geology with the growth of the railroad industry with a short description of how it impacted BNSF’s Cascade Tunnel’s ventilation system. \nThe advent of the Industrial Revolution accelerated the development of the science of geology\, and the growth of the railroad industry closely followed. A quick look at both of these disciplines over the past 200 years reveals a fascinating back and forth which resulted in amazing advances for both. \nFor instance\, geologists found the coal and then the railroads transported this coal to locations where people worked and lived. And coal mines virtually dictated where the rail line should be built. Comparisons between the two efforts continue to the present day and Bill will outline some of the current challenges. \n  \nIn 1995\, Bill was heavily involved in the installation of a new ventilation system for BNSF’s Cascade Tunnel. Ventilation of the tunnel has been an issue since the first Cascade Tunnel opened in 1900. Bill will describe how BNSF ensures safe operations in the current (second) Cascade Tunnel\, the longest railroad tunnel in the United States. \nBill Burgel is a Professional Geologist Registered in Oregon and Idaho. He retired in 2015 after a successful 45-year career in the railroad industry. He worked for several railroads nationwide in both the engineering and operating departments. While working for the railroad\, his interest and training in geology was often called upon to resolve landslide issues and rerouting studies\, implement early earthquake warning strategies\, and conduct numerous long railroad tunnel analyses. Bill has given numerous presentations on rail issues as well as earthquake preparedness and topics pertaining to regional geology to local audiences throughout the Pacific Northwest and on cruise ships.

SUMMARY:Expansion of Early Roads in the US West
DESCRIPTION:On Tuesday October 14\, Dr. E. F. Cater\, Director of the Douglas County Historical Museum in Waterville\, will present a talk\, “Expansion of Early Roads in the US West.” The program starts at 7:00 PM\, at the Wenatchee Valley Museum and Cultural Center\, 127 South Mission\, in Wenatchee. Zoom link for those who cannot attend in person: https://us02web.zoom.us/j/8185554795 Meeting ID: 818 5554 7958 \nWestern roads developed by push and shove. Business people and shippers built some of the first usable roads. They needed to get wares to market. Others built ways to get to town to buy those goods. \nBuilding new roads\, and connecting roads\, was difficult and expensive. No entity wanted to do that. Not the Federal government\, nor the states\, not the counties. They got pushed into road-building. What happened? \nAround 1912\, the introduction of the automobile\, especially the Model T\, spurred the United States into building auto-routes adequate for travel. There were no transcontinental highways. Many states didn’t even connect with one another. \nLocally\, the Yellowstone Trail eventually passed through Waterville\, Wenatchee\, Monitor\, Cashmere\, and over Blewett Pass. We will learn about that road. \nClick the link below to see the first 3 minutes of the presentation:\nhttps://youtu.be/Htov6YXW6L8?si=ixgoJkN63zfs1mWi \nThe program is free and open to the public. \nSwitchbacks on Blewett Pass\, 1910

SUMMARY:The Ancient Ice Age Floods in the Pacific Northwest
DESCRIPTION:The Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute will meet Tuesday\, February 11 at 7:00 PM. Our speaker will present remotely via Zoom from Portland. Those not computer- or Zoom-savvy can attend in-person for a live screening at the Wenatchee Valley Museum and Cultural Center\, 127 S. Mission\, Wenatchee. Or at home using Zoom link    https://us02web.zoom.us/j/81855547958  Meeting ID: 818 5554 7958 \nDr. Scott Burns\, Professor Emeritus of Geology at Portland State University\, is a researcher\, teacher\, and story-teller of Pacific Northwest Geology. He will discuss “The Ancient Ice Age Floods in the Pacific Northwest.” \nWe know that Ice Age Floods have inundated the Pacific Northwest over the past 2.8 million years. But we primarily concentrate on the last ones\, the Missoula Floods\, that occurred between 20\,000-15\,000 years ago. That’s because the Missoula Floods left the most visible record; they obliterated nearly all the evidence of earlier inundations. Current research\, however\,  shows an unfolding story of the many torrents that preceded the Missoula Floods. Erica Medley\, an MS student of Dr. Burns\, discovered many deposits of these rarely discussed ancient floods. Dr. Burns\, a most dynamic speaker\, is here to talk about those older ones! \nThe program is free and open to the public.

SUMMARY:The Rush to Oregon Territory
DESCRIPTION:The Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute will meet Tuesday\, October 8 at 7:00 PM\, at the Wenatchee Valley Museum and Cultural Center\, 127 S. Mission\, Wenatchee. Or via Zoom link https://us02web.zoom.us/j/84520197937 \nOur speaker is Dr. E.F. Cater\, Director of the Douglas County Museum in Waterville. Dr. Cater will explore “The Rush to Oregon Territory\,” how the twisting and turning of 19th-century society crossed up with the Ice Age Floods. \nAn odd happenstance occurred when a delegation of Salish men from the Walla Walla area traveled to St. Louis. They sought out their old friend\, General William Clark\, with an unusual question. This little spark caused a rush to Oregon Territory for reasons different than what Manifest Destiny has led us to believe. \nAnd the stirring of this pot brought the discovery of fantastic geological features like Grand Coulee. Join us as we take a look at Western Expansion. \nThe program is free and open to the public. \n[Illustration: Lewis and Clark on the Trail 1804\, by Michael J. Deas]

SUMMARY:Mapping the Glacial Legacy of the Pacific Northwest
DESCRIPTION:The Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute will meet Tuesday\, August 13 at 7:00 PM\, at the Wenatchee Valley Museum and Cultural Center\, 127 S. Mission\, Wenatchee. Or via Zoom link https://us02web.zoom.us/j/84520197937 \nOur speaker is Daniel Coe\, graphics editor for the Washington Geological Survey in Olympia; and an editor for the North American Cartographic Information Society’s Atlas of Design. He will talk about “Mapping the Glacial Legacy of the Pacific Northwest.” \nGlaciers have shaped much of the Pacific Northwest’s landscape over the past 15\,000 years. The Cordilleran ice sheet\, repeated ice age floods\, and expansive alpine glaciation have left their distinctive fingerprints on the topography of our region. Geologists and cartographers have been mapping and interpreting glacial landforms since the late 19th century. In the past decade\, the Washington Geological Survey has created new maps that build upon this rich cartographic history by fusing older datasets and techniques with modern insights and technology\, such as lidar. \nUsing both historical and modern maps\, this presentation will be a visual journey through the Pacific Northwest’s glacial past and present. \nYou can see Daniel’s work at dancoecarto.com \nThe program is free and open to the public. \n

SUMMARY:Exploration of Geomorphic Features in Lake Chelan with an Underwater Remotely Operated Vehicle (ROV)
DESCRIPTION:The Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute will meet Tuesday\, June 11 at 7:00 PM\, at the Wenatchee Valley Museum and Cultural Center\, 127 S. Mission\, Wenatchee. Or via Zoom link https://us02web.zoom.us/j/84520197937 \nOur speaker will be Philip Long of the Lake Chelan Research Institute (LCRI). Phil will talk about “Exploration of Geomorphic Features in Lake Chelan with an Underwater Remotely Operated Vehicle (ROV)” \nSwath bathymetry\, chirp sub-bottom reflection profiles\, and sediment cores…. These were techniques recently used by the U.S. Geological Survey (June 2023) to collect data from Lake Chelan\, WA\, The resulting information has provided insights into late- and post-glacial history of Lake Chelan. In addition\, LCRI’s ROV dives have distinguished bedrock from till on lake bottom sediment profiles\, and have directly observed landslide scarps\, debris aprons\, and other geomorphic features of interest to many of us here. Some of the features on the bottom of Lake Chelan resemble surface glacial features we are familiar with on the Waterville Plateau! Moraines\, kames\, drumlins\, kettles\, underwater landslides…. \nFind out what’s going on at the bottom Lake Chelan! \n  \nThe program is free and open to the public. \nContact information:\nKen Lacy\n1geospiracle2@gmail.com\n(509) 787-9755 \nSusan Freiberg\nWenatchee Valley Erratics Publicity\nwenvalerratics@yahoo.com

SUMMARY:JT Pardee and the Lake He Discovered - Talk by Bill Burgel
DESCRIPTION:The Wenatchee Valley Erratics Chapter’s next program will be Tuesday\, February 13 at 7:00 PM. Our speaker will present live at the Wenatchee Valley Museum and Cultural Center\, 127 S. Mission\, Wenatchee. There is also a Zoom link so one can watch remotely: https://us02web.zoom.us/j/84520197937 Webinar ID: 845 2019 7937. \nJoseph T. Pardee\nBill Burgel is coming up from Portland to tell us about “Joseph T. Pardee and Glacial Lake Missoula.” Pardee was a USGS Field Geologist whose expertise was in Western Montana\, where he was raised and worked for years. He was the first to recognize\, around 1910\, the features of a vast\, ancient Glacial Lake Missoula. \nIn the 1920s\, working independently of Pardee\, Harlan Bretz had determined from field evidence\, that only an extraordinarily huge flood\, or floods\, could have carved out the Channeled Scablands and the big coulees associated with them in eastern and central Washington. But he didn’t know the source of the water. Pardee quipped that he “knew the source of Bretz’ water.” In 1925\, he suggested to Bretz that the draining of a glacial lake could account for the magnitude of water flows needed to create the Scablands and coulees. \nThe program is free\, and open to the public.\n—- \nBill Burgel worked in the railroad industry for 40 years\, in engineering and operations. With his background and training in geology\, he was often called upon to resolve landslide issues and rerouting studies\, earthquake warning strategies\, and to conduct long tunnel analyses. \nContact information:\nBrent Cunderla – Erratics Chapter President\ncunderla@nwi.net  (509) 860-6067 \nSusan D.

SUMMARY:Dr. Ralph Dawes - "Glaciated Landscape Beneath the Okanogan Ice Sheet"
DESCRIPTION:The Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute’s next program will be on Tuesday\, October 10 at 7:00 PM at the Wenatchee Valley Museum and Cultural Center\, 127 South Mission St.\, Wenatchee. \nDr. Ralph Dawes\, Professor of Earth Science\, Wenatchee Valley College\, will discuss the “Glaciated landscape that formed beneath the Okanogan Lobe of the Cordilleran Ice Sheet” in north central Washington. This area\, including Douglas County north of Waterville and all of Okanogan County\, was studied early in the last century by well-known geologists J Harlan Bretz\, Richard Foster Flint\, and Aaron C. Waters. How the ice sheet shaped the landscape underneath it was a source of controversy back then\, and remains a subject of scientific debate today. \nDr. Dawes takes a four-part approach addressing the origin of the Okanogan landscape: \n\nRead published geologic studies of the Okanogan Lobe and Cordilleran Ice Sheet;\nlearn latest theories of how ice sheets create landforms;\nuse current online map data; and\nground-truth to examine the evidence itself.\n\nYou can attend in-person at the Museum\, or via Zoom link https://us02web.zoom.us/j/84520197937  Please sign in at 7:00 PM\, October 10! \nThe program is free and open to the public.
