Surficial Geology and Distribution of Post-Impoundment Sediment in Las Vegas Bay, Lake Mead

Figure 13.   Seismic profiles showing different examples of the post-impoundment sediment fill. A and B show places where the sediment is thicker and has some internal reflectors. C shows the thin sediment cover blanketing only the floor of the submerged valley, and D shows foreset beds in what is interpreted to be a delta off Government Wash that formed in 1968. Profile locations shown in Figure 2.
