Abstract
The Palouse is an Inland Northwestern ecoregion with loess hills created by aeolian processes related to Pleistocene glacial events. Eastern Washington University’s Prairie Restoration Project aims to restore a 120-acre site located in Cheney, Washington. EWU is gradually seeding bunchgrasses and perennial forbs to increase biodiversity of the site, which will be used for educational and recreational purposes. The objective of this project was to determine to what extent the engineering properties of soil on the site varies along a slope. To determine if location on the slope affects soil properties on the site, we sampled and performed a geotechnical analysis on mid-slope soil using ASTM International standards. We then compared the engineering properties of the mid-slope soil to those of the upper slope and slope base.
