Abstract : Preshot and postshot field investigations of the Sedan crater were made to obtain information on the change in engineer ing properties of the subsurface soil adjacent to the crater, and to determine the engineering properties of the important physiographic features of the crater such as ejecta and fallback materials. Field investigations included geological studies of the area, undisturbed and general sample borings, and geophysical logs. Subsurface soils consisted of desert alluvium, a relatively dense mixture of silt, sand, and gravel. The behavior, including both immediate and longterm stability, of the slopes forming the Sedan crater is a function of the particular character of the subsurface soils and environmental factors in the area. Consequently, the results obtained at Sedan may not be applicable to other areas.
