Assessing Weathering of Vertical and Horizontal Limestone Tombstones in Washington State

Author(s) Mary Powers Faculty Mentor(s) Lisa Ely (Geological Sciences) Abstract Rain, wind, and other processes modify Earth’s landscape and rock material over time. Examining tombstone weathering is a way to measure the weathering rates of rock. The date listed on the tombstone provides the approximate… Read More »Assessing Weathering of Vertical and Horizontal Limestone Tombstones in Washington State

Identifying the trace element chemical fingerprint of blue colored quartz stones

Author(s) Sydney Dale Faculty Mentor(s) Angela Halfpenny (Geological Sciences) Abstract Ellensburg Blues are a locally sourced blue quartz that retail for a higher price than blue quartz samples from other localities. We hypothesize that Ellensburg Blue samples have a distinct trace element fingerprint in comparison… Read More »Identifying the trace element chemical fingerprint of blue colored quartz stones

Evaluating the role of deep Earth processes in mineral deposit formation, North Cascades, Washington.

Author(s) Colton Bell Faculty Mentor(s) Christopher Mattinson (Geological Sciences) Abstract The demand for new technologies and clean energy sources has brought an increase in demand for mineral resources to supply the elements needed. Sulfide minerals are the source of many economically significant elements, such as… Read More »Evaluating the role of deep Earth processes in mineral deposit formation, North Cascades, Washington.

Effects of in-stream large wood on shallow aquifer recharge at Indian Creek in central Washington

Author(s) Stephen Bartlett Faculty Mentor(s) Lisa Ely (Geological Sciences), Carey Gazis (Geological Sciences) Abstract Restoration of streams and floodplains using large wood is now common practice in Washington. The primary goals are to restore aquatic habitat, and riparian ecosystems and reconnect streams to floodplains. A… Read More »Effects of in-stream large wood on shallow aquifer recharge at Indian Creek in central Washington

Long-term geomorphic effects of the Glines Canyon Dam removal on the Elwha River, WA, USA

Author(s) Alyssa DeMott Faculty Mentor(s) Lisa Ely (Geological Sciences) Abstract Over the last few decades, it has become well-understood that dams inflict serious damage to riverine ecosystems. Because of this, dam removals are becoming more common. The Elwha River in western Washington once provided vital… Read More »Long-term geomorphic effects of the Glines Canyon Dam removal on the Elwha River, WA, USA

Using remote sensing techniques to identify geomorphic modifications caused by landslide tsunamis

Author(s) Trent Adams Faculty Mentor(s) Breanyn MacInnes (Geological Sciences), Jennifer Lipton (Geography), Lisa Ely (Geological Sciences) Abstract When a large landslide falls into a deep body of water it can produce giant tsunami waves capable of causing widespread geomorphic change to landscapes. What changes occur… Read More »Using remote sensing techniques to identify geomorphic modifications caused by landslide tsunamis
