Abstract: The paper gives information on the stability of clay shale slopes from studies of the geology and history of sliding, determination of physical properties from laboratory tests, and stability analyses of the slopes. Slopes in five different formations along the upper Missouri River were studied. The most expedient manner to view the stability characteristics of these slopes was through empirical slope charts. Design experience in the study area had used similar approaches with success when local site geologic and hydrological conditions were considered. In the Panama study, detailed records were available to reconstruct the sliding history and allow limit type analyses to be performed. Both approaches can be utilized to determine design slopes by giving proper recognition to the limitations of each.
