2020-01-18 Jeff Tepper — Accretion of the Olympics and Birth of the Cascades

From the Accretion of the Olympics to the Birth of the Cascades: The Eocene Transformation of Washington Geology About the lecture  Dr. Jeffrey Tepper showed how Port Townsend lies between two mountain belts with very different origins, the oceanic Olympic Mountains to the west and the continental Cascade Range to the east. But despite their contrasting traits, the histories of these two chains are intimately connected. He explored how the arrival of the Siletzia terrane about 52 million years ago led to a profound geological transformation of the Pacific Northwest. Over a 10 million year interval in the mid-Eocene (~54-44 Ma),… Read more2020-01-18 Jeff Tepper — Accretion of the Olympics and Birth of the Cascades

2022-01-08 Carolyn Driedger, USGS—Hazards from the Nevado del Ruiz and Mount Rainier volcanoes

The Lecture Nevado del Ruiz (Colombia) and Mount Rainier (US) exist a hemisphere apart, but they both project similar hazards for communities downstream.  Central to their stories is the development and continued presence of weak and collapse-prone hydrothermally altered rock, and perennial covers of glacier ice and snow. Slopes of both volcanos are mantled by loose rock debris that can be remobilized to initiate lahars. At both volcanoes, five major glaciofluvial rivers flow down narrow valleys to lowland areas that support large human populations. More than a 150,000 persons live in areas at risk of lahars that could emanate from… Read more2022-01-08 Carolyn Driedger, USGS—Hazards from the Nevado del Ruiz and Mount Rainier volcanoes

2023-04-29 Skye Cooley: Calcrete and Soil-Climate Evidence

The Lecture: Soil-climate evidence for timing of the Cascade uplift and creation of its rain shadow Calcrete is a CaCO3-rich hardpan paleosol that forms in dry, stable landscapes of the world. Calcrete in eastern Washington cements a 20-m-thick interval across three geomorphic domains: Palouse Hills, Channeled Scablands, and Yakima Fold Belt. The sheet-like calcrete deposit encloses ancient Scabland flood gravels and defines a regional paleosurface that has been bent and broken by Quaternary faults. Calcrete overprints primarily lowland alluvial deposits (ancestral Columbia-Snake River floodplain) and basaltic alluvial fan gravels shed from fault-bounded ridges. Thick layers of pedogenic carbonate accumulated during… Read more2023-04-29 Skye Cooley: Calcrete and Soil-Climate Evidence


2023-05-13 Vince Matthews — Global Scramble for Natural Resources

Vince Matthews, former director of the Colorado Geological Survey and now a consulting geologist in Wisconsin, spoke on the Global Scramble for Natural Resources. This was a ZOOM broadcast Saturday, May 13, 2023. The Lecture During the 1990s, the world’s most populous nations—China and India–were unleashed from Communist and Socialist regimes, respectively. The first decade of the 21st Century saw China’s GDP grow at more than 10 percent per year and India’s at 7-9 percent. Both are drastically increasing their use of all natural resources. Although they have resources of their own, they are insufficient to meet their internal demand…. Read more2023-05-13 Vince Matthews — Global Scramble for Natural Resources


2024-03-23 Brian Sherrod — New Findings on Earthquakes of Salish Lowland with Tree Analysis

We enjoyed hearing in-person USGS geologist, Dr. Brian Sherrod, on February 24, 2024 and by Zoom March 23. THE LECTURE:  High-resolution dating of a multi-fault earthquake and earthquake recurrence in the Salish Lowland Dr. Brian Sherrod discusses new evidence for a multi-fault rupture. This rupture occurred along the Seattle (SFZ) and Saddle Mountain (SM) faults in the winter of 923-924 CE. He presents new evidence for a proto-historic earthquake on the Seattle fault (in the 1830s), and he talks about recurrence of large earthquakes in the Salish Lowland. He employs photographs, USGS mapping, lidar measurements, charts, and graphs to elaborate… Read more2024-03-23 Brian Sherrod — New Findings on Earthquakes of Salish Lowland with Tree Analysis


2024-04-20 Ralph Haugerud – Glacial Landscape of Puget Sound

Post-Mortem of Southern Cordilleran Ice Sheet The Lecture: Post-mortem of the southern Cordilleran Ice Sheet Death of an ice sheet can have many causes, as shown by retreat of the southern Cordilleran Ice Sheet about 15,000 years ago. East of the Cascades, the margin of active south-flowing ice retreated north as less snow fell and more melted. West of the Cascades, the Juan de Fuca lobe of the ice sheet appears to have floated away in response to rising sea level, perhaps without a proximal climatic cause. Collapse of the Juan de Fuca lobe diverted ice from the Puget lobe, which consequently stagnated… Read more2024-04-20 Ralph Haugerud – Glacial Landscape of Puget Sound

Atwater, Brian

When Americans think of earthquakes, they are likely to think of California. Laced with active faults and subject to frequent quakes, the state certainly stands out on national maps of seismic hazards. But the current maps also highlight seismic hazards farther north, chiefly in Washington and Oregon, which became known since the 1970s through a remarkable series of discoveries in the United States and Japan. USGS geologist Brian Atwater played key roles in these discoveries by identifying, in coastal geology, the traces of earthquakes and tsunamis going back thousands of years. The 1980 eruption of Mount St. Helens called attention… Read moreAtwater, Brian

I teach majors’ courses in geomorphology and engineering geology, and a great variety of general education courses in introductory geology. My prime interest, at the moment, is “Geosciences and the Arts.” I have authored a number of college texts, have produced geologic videos, published the requisite number of articles in professional journals, and done those things expected of a university professor. What I love most, however, is teaching, and the exciting interactions possible through that venture. In Jan. of 2015,… Read morePestrong, Ray

Reed, Kitty

Kitty (Katherine Milmine) grew up in New England but saw the Rocky Mountains in about 1950 at age 12. Going west was then the goal. But her geology degrees from Bryn Mawr and Harvard came with no fieldwork at all. She married a fellow grad student (Bruce Reed) and, in 1962, moved to California, where she soon started a career in tech editing with the USGS. Eventually, the family settled in Anchorage, AK. Summers often found them in remote field camps. She came to Olympia, WA, in 1986 to edit for what is now the Washington Geological Survey (now a… Read moreReed, Kitty

My initial projects at USGS were mapping the surficial geology of the eastern Snake River Plain, Idaho, and pursuing studies of Quaternary stratigraphy and faulting along the Wasatch Front in Utah. The latter resulted in a greatly… Read moreScott, William (Willie)

Walsh, Tim

An era is ending at the Washington State Department of Natural Resources. After a very productive 38-year career Tim Walsh is retiring in 2018 from the Washington Geological Survey. It seems like a long time to us, but to geologists, 38 years is a standard rounding error. Tim Walsh began his career at DNR in 1980 as a project geologist for the Survey mapping and assessing coal resources in Washington. Shortly after his hire, Tim flew a reconnaissance flight to observe smoke coming from Mount St. Helens. The small plane carrying the California native could barely top the mountain’s then… Read moreWalsh, Tim
