Abstract
Our sampling location was the Palouse Prairie rolling hills outside Eastern Washington University. The purpose was to examine the soil types within the Palouse Prairie, where EWU is working to restore the prairie to its original ecosystem. We analyzed a soil sample located at the base of a sloping hill, while other groups examined samples from the slope top and middle slope to compare how soil types vary with water movement and hill structure. Our sample was PP-16, and the testing followed ASTM standards to identify soil properties that may aid in construction and restoration of the Palouse Prairie, as well as to understand differences in soil types along the hillslope. This information will help mitigate slope failure and reduce potential harm.
