Abstract
Eastern Washington University is located on the Palouse, a region in the Inland Northwest distinguished by rolling hills formed by wind blown loess of glacial origin. Due to agriculture, only 1% of this region still maintains its natural habitat. EWU has dedicated a third of its land to restore a portion of the Palouse to its natural state in a multidisciplinary project called the Palouse Prairie Restoration Project. We collected soil from the north face of a hill on the project site to determine its geotechnical properties. We conducted ASTM standard tests on our sample to determine specific gravity, Atterberg Limits, particle size distribution, optimal water content for compaction, and unconfined compressive strength. This information will help EWU develop infrastructure on the site including trails, visitor center, amphitheater, and parking lots.
