An Examination of Washington\u27s Mima Mounds Through LiDAR Analysis
A study of Mima Mounds and Mima-like mounds which are common to the Scabland areas of Washington and Northern Oregon. A specific look at the Rock Creek Recreation Area near Sprague, WA, using LiDAR as a beginning point to quantify and categorize the mound\u27s numbers, and their unique geomorphology. Geological and Biological theories are examined as possible explanations of the mound formations and maintenance on the landscape. Geospatial tools are used to analyze the frequency of the mounds and their clustering behaviors. Further research will be needed to improve our understanding of the mounds and the underlying geologic and biologic triggers
One Year of Analysis of PFAS Contamination in Surface Waters of the West Plains Region of Spokane County
The West Plains has been significantly impacted by PFAS contamination due to the decades-long use of aqueous film-forming foam (AFFF) for firefighting training at both Fairchild Air Force Base (FAFB) and the Spokane International Airport (SIA). Groundwater contamination is significant, but less work had been done to understand contamination in surface waters. We now have over a year of data with most locations were sampled seasonally. Though FAFB and SIA are likely sources for some of the contamination, other, smaller sources exist. Surface waters are important to study as they form the boundaries of the West Plains and often function as the transport mechanisms and sinks for PFAS contamination
