Delineation Of Buried Valleys Using Integrated Geophysical Techniques

In northeastern Greene County, Ohio, Beaver Creek (a very small<br>stream) flows through a valley whose width exceeds a mile in some places.<br>Orton (1874) recognized that this valley was once the site of a much<br>larger river. Kulibert (1979) established that during early Wisconsin<br>glaciation the valley was occupied by the much larger Mad River. The<br>valley is also partly superimposed on the preglacial Hamilton River Valley<br>(Norris et al., 1950). Both valleys, the ancestral Beaver Creek and<br>Hamilton River, are currently filled with sediments. This study is a<br>detailed multi-faceted geophysical profile study of the ancestral Beaver<br>Creek Valley where it exists cut into the west side of the Hamilton River<br>Valley (Figure 1).
