Abstract
The Palouse Prairie Restoration Project is devoted to actively restoring 120 acres of the EWU campus to its natural state of Palouse prairie habitat. This sustainability initiative provides educational and research opportunities, as well as recreational and cultural connections for students, faculty, and the community. We collected soil sample PP-9 from the upper area of a loess hill along its north face near the EWU water tower, located at: 47.49385º N, -117.59299º W with an elevation of 2531ft. The rolling hills of the Palouse Prairie soil are composed of loess, a wind-blown silt that was deposited in Eastern Washington during the last Ice Age. We conducted ASTM standardized tests on soil sample PP-9 to determine its geotechnical properties including specific gravity, particle size distribution, Atterberg Limits, optimal water content for compaction, and unconfined compressive strength. This information is designed to help with site development and management of upcoming infrastructure initiatives including a visitor center, amphitheater, pathways, and parking areas.
