01-09-2021 Scott Burns—Tasting Terroir

Tasting Terroir—Geologic and climate  influences on wine flavors in the Pacific NW (a talk and tasting) The Lecture To begin with, Scott will discuss the factors that affect wine flavors, concentrating on the climate and geology of the region.  Oregon and Washington are the number 3 and 2 states in number of wineries in the United States and just across the border, B.C. is the number 2 province in Canada for wine production.  Scott will concentrate on SE Washington and Willamette Valley in Oregon, but will also discuss NW Washington, SW Oregon, and British Columbia (including Vancouver Island which has a solid… Read more01-09-2021 Scott Burns—Tasting Terroir

02-27-2021 Ben Goldfarb, Dam It—How beavers shape the landscape

The Lecture Our featured speaker on Saturday Feb, 27th is Ben Goldfarb. In Eager: The Surprising, Secret Life of Beavers and Why They Matter, environmental journalist Ben Goldfarb reveals that our modern conception of a healthy ecosystem is wrong, distorted by the fur trade that once trapped out millions of beavers from North America’s waterways. The consequences of losing beavers were profound: ponds drained, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of “Beaver Believers”—including scientists, ranchers, and passionate citizens—recognizes that ecosystems with beavers are far healthier than those without them. From the Nevada deserts to the… Read more02-27-2021 Ben Goldfarb, Dam It—How beavers shape the landscape

04-10-2021 Trevor Contreras, Geology and the Art of Stone Carving

Geology and the Art of Stone Carving The Lecture Many members of the Northwest Stone Sculptors Association (NWSSA), including me, use Washington rocks in their art. In this talk, I’ll give an overview of this state’s geological setting  that provide these stones and describe the connections among basalt, dunite, jade, and the glacial erratics that we work with. I’ll highlight a few of my favorite sculptors, talk about some of the stone they work, and touch on tools and techniques we use to sculpt these locally sourced stones. In 2009 King County geologist Greg Wessel curated a geology and art… Read more04-10-2021 Trevor Contreras, Geology and the Art of Stone Carving

05-20-2020 Michael Machette — Geology in Our Neighborhood

The Lecture (Starts at around 23 minute mark) This presentation on May 20, 2020 was made as part of Nature in Your Neighborhood, a six-part series of Zoom Lectures sponsored by the Jefferson Land Trust (add link here).  It describes the general geologic history of the Quimper Peninsula during the latest Pleistocene (past 20,000 years) and Holocene (past 11, 500 years).  It focuses on three themes: Glacial meltwater channels — Chimacum Valley The Bluffs Downtown Glacial Erratics with a special challenge The presentation is about an hour long and features geologic interpretation of glacial deposits in the Port Townsend area….

05-22-2021 Jennifer Pierce—Wildfires, Climate and Erosion

On Saturday May 22, 2021 @ 4 pm, Dr. Jennifer Pierce of the Dept. of Geology at Boise State University will present a Zoom lecture on “Wildfires, Climate and Erosion in the past, present and future”.  Jennifer has been working on these topics since graduate school and will integrate these three subjects with reference to forests of the Northern Rocky Mountains. Although her studies have been concentrated in the Northern Rockies, the lessons learned apply well to the relatively arid regions of the West. Since she is speaking in late May, we could be into our fire season here in… Read more05-22-2021 Jennifer Pierce—Wildfires, Climate and Erosion

10-03-2020 Terry Wallace — Gold: A Journey from the Big Bang to the Amazon (Zoom)

Gold—A Journey from the Big Bang to the Amazon Click here for  video Gold is one of the most fascinating of the 5,400 mineral species on Earth and no mineral (or metal) evokes more emotion, but gold also has an incredible scientific story: a gold nugget is made of material that was not born in our planet or even our solar system. In this talk, world-renowned geophysicist Dr Terry Wallace discusses how the metal was created, how it came to be found on Earth, and the spell it has cast over humankind.  The lecture was broadcast via Zoom on Oct. 3,… Read more10-03-2020 Terry Wallace — Gold: A Journey from the Big Bang to the Amazon (Zoom)

10-08-2020 Michael Machette –Your soil: it’s all about geology (YouTube recording)

Your soil— it’s all about geology (presented by Port Townsend Master Gardeners) Click here for  video. The lecture If you didn’t see Michael’s hour-long Zoom presentation, it will be available for 6 months on WSU’s YouTube channel (click above).  Michael discussed the local geology ofPort Townsend and the larger Quimper Peninsula and geology effect on the soils in your garden. Topics included soil forming factors, the importance of and way to determine the texture of your soil, and the relationships between surficial geology and soils, with examples from Port Townsend and the Chimacum Valley.  All of the soils in this region are young… Read more10-08-2020 Michael Machette –Your soil: it’s all about geology (YouTube recording)

11-14-2020 Pat Pringle — Buried and Submerged Forests of the Pacific Northwest (Zoom recording)

Buried and Submerged Forests of the Pacific Northwest—Witnesses to Ancient Earthquakes, Landslides, and Volcanic Eruptions. How much we know about the Pacific Northwest’s post-Ice Age geologic events has grown rapidly in recent decades. The discovery and study of buried and submerged forests-Victims of past catastrophes, has opened the door to new understanding. Testing techniques such as Carbon 14 wiggle matching and dendrochronology (tree-ring dating) now allow more precise dating of the geological past as well. These capabilities are revolutionizing our understanding of the history, behavior, and effects of past volcanic eruptions, regional earthquakes, major landslides, and (to a limited extent) regional climate history and fluctuations. We will take… Read more11-14-2020 Pat Pringle — Buried and Submerged Forests of the Pacific Northwest (Zoom recording)

12-12-2020 Will Gallin — Geologic Carbon Sequestration in Washington State (Zoom recording)

Will Gallin — Geologic carbon sequestration in Washington State The Subject What is carbon sequestration?  What are the benefits and risks of geological carbon sequestration in Washington State? And what is technologically possible and economically feasible? We will examine these questions and explore the current state of the science. The Washington Geological Survey is part of a three-year partnership of 13 western states, stimulated by the U.S. Dept. of Energy (DOE). The member institutions, consisting of state geological surveys, universities, and national laboratories (under Dr. Robert Balch of New Mexico Tech), will identify commercially viable interstate networks between carbon emitters and potential subsurface carbon reservoirs….
