Electrical Resistivity Tomography (ERT), Spontaneous Potential (SP), Multichannel Analysis of Surface Waves (MASW) and Seismic Refraction Tomography methods have been used to provide valuable information on the seepage pathways leading to dewatering of Lolo Creek and the subsurface lithology of the area. Results from the MASW and seismic refraction tomography studies show a bedrock elevation of about 35 m close to Highway 93 and about 27 m at the end of the 288 m East-West seismic line running through Lewis and Clark Drive. ERT results show a shallow high resistive geolectric layer underlain by low resistive layers. The Eocene bedrock …
