Geologic map of Quaternary deposits south of Grays Harbor and near Willapa Bay, southwestern Washington coast
(2021-05)New 1:24,000 scale geologic mapping on the southwestern Washington coast, south of Grays Harbor and along Willapa Bay, indicates nine Quaternary units in what was previous mapped as a single unit. These units include ... -
Opportunities for Geologic Carbon Sequestration in Washington State
(2020-06)Washington State has a goal to reach net-zero greenhouse gas emissions by 2050. To achieve this goal, active sequestration of carbon dioxide will be required. This report reviews processes of geologic carbon sequestration ... -
Quaternary Deformation of the Hog Ranch-Naneum Anticline Region, Northeast Kittitas Valley, Washington
(2020-03)Geomorphic evaluation of the northeastern Kittitas Valley and Hog Ranch-Naneum Anticline (HRNA) region provides new insight into the recent deformation and uplift by Quaternary faults along the northern range front of ... -
Optimizing Arsenic Removal in a Groundwater Treatment Cell
(2020-03)The goal of this research is to investigate geochemical factors on arsenic removal from groundwater in a groundwater treatment cell. The treatment cell is near Metaline Falls, WA, and is operated by Geosyntec Consultants. ... -
Modeled tsunami in Lake Washington from hypothetical ruptures on the Seattle Fault
(2020-03)Tsunami deposits from an earthquake on the Seattle fault have been found around the Puget Sound area. Tsunami modeling has been conducted in Puget Sound with the Seattle fault as the initiating event, however published ... -
Variations in Atterberg Limits for the Lawton Clay with Acidic Pore Fluids
(2020-03)The physical mechanisms that cause slope failure involving the Lawton Clay in the Puget Lowland have been well studied; however, the physio-chemical mechanisms, specifically acidic pore fluid are poorly understood. This ... -
The Lost Lake Landslide: Evidence for an Earthquake-Triggered Landslide Vashon Island, Washington
(2020-03)I address the large-scale stability and potential past and future triggers of the Lost Lake Landslide on Vashon Island, one of the largest mapped landslides in the Puget Lowland. I focus on three landslide triggers; ... -
Port Gamble SíKlallam Tribe Coastal Analysis: Shoreline Change and Extreme Water Levels
(2020-03)The Port Gamble SíKlallam Tribe (PGST) relies on coastal resources for recreation, cultural enrichment, spiritual enhancement, and food. Shoreline change and extreme water levels associated with climate change will impact ... -
Paleowind Direction and the Regional Pattern of Grain Size and Atterberg Limits of Loess in Adams and Lincoln Counties, WA
(2020-03)Loess is a fine-grained floury material carried by wind. The properties of loess are important for infrastructure, agriculture, and construction planning in areas where it is abundant. Eastern Washington is one such ... -
Landslide Ages and Implications for a Marine Terrace at Rialto Beach, WA
(2020-03)Holocene landslides and marine terraces at Rialto Beach, on the Olympic coast of Washington state, may provide clues about the response of the Pacific coastline and adjacent hillslopes to Cascadia subduction zone (CSZ) ... -
Characterizing the style, composition, and timing of Cedar River Landslide Complex
(2017-03)The Cedar River Landslide Complex (CRLC) is a series of debris flowslides about 3 km down river from the Masonry Dam at Chester Morse Reservoir in the Cedar River Municipal Watershed, the source of drinking water for 1.4 ... -
A comparative Analysis of Grain Size distributions and Cross Sections using an Oblique Photoset on the Nisqually Riverbed Adjacent to Longmire In Mount Rainier National Park
(2019-03)Collecting cobble counts and gathering cross sections out in the field can be a tedious and time consuming process. An attempt was made at expediting this process using structure from motion technology to create an orthophoto ... -
Geomorphic Reconstruction of Alki Point in West Seattle Based on Chronostratigraphic Relationships of Mid-Late Holocene-Aged Intertidal Deposits
(2019-12)A tombolo may have tied a bedrock knoll at the western tip of Alki Point to the mainland before a large magnitude 7 or greater earthquake ruptured within the Seattle fault zone, resulting in ~23 ft of uplift at Alki Point ... -
Using the Rockfall Activity Index to assess the impact of scaling on rock fall activity at Glitter Gulch, Alaska
(2019-06)This research examines terrestrial-laser scan data on a road cut in the Glitter Gulch area of Alaska, immediately preceding and following a slope stabilization project, noting changes in rock fall and comparing the work ... -
Predicting the Position of Fault Strands through Borehole Correlation of the Top of Tertiary Bedrock in the Seattle Fault Zone, Seattle, Washington
(2019-12)Only a few strands of the Seattle Fault Zone have been identified on land in Seattle, Washington due to heavy manipulation of the landscape by repeat glaciations, geomorphic reworking, and the interference of the growing ... -
Evaluating River Profile Geometries to Identify Evidence of Active Deformation Associated with the Doty Fault Zone in Southwest Washington
(2019-06)In 1996, 2007, and 2009, flooding of the Chehalis River near the Town of Chehalis in southwest Washington severely impacted infrastructure and property. Damage was such that Interstate 5, the major transportation throughway ... -
Evaluation of Subsurface Impacts on Occurrence of Sand Boils from the 2001 Nisqually Earthquake in the SoDo Neighborhood of Seattle, Washington
(2019-06)The 6.8 magnitude Nisqually earthquake occurred on February 28th, 2001 causing liquefaction in multiple areas of Seattle, mostly in the SoDo neighborhood. Following the earthquake, scientists recorded field observations ... -
Analysis of the Timing of Building Displacement during Intense Seismic Shaking for three Earthquakes, 2001 Mw 6.8 Nisqually (Washington State), 2017 Mw 7.1 Puebla (Mexico), 2018 Mw 7.1 2018 Anchorage (Alaska)
(2019-06)Localized intense ground shaking from strong earthquakes pose significant hazards to humans including building damage that may lead to structural failure and possible collapse. Building failure can cause harm or ...
