Surficial Geology and Distribution of Post-Impoundment Sediment in Las Vegas Bay, Lake Mead
Figure 8. Four profiles from the delta and prodelta area off the mouth of Las Vegas Wash. Profiles A and B are strike lines, one on top of the delta (A) and one beyond the edge of the delta. The approximate depth of the preimpoundment valley floor is shown on profile A. Profiles C and D are dip lines that show the flat delta top, the steep delta front, and flat prodelta area. Note the topset bed that is buried by less than 1 m of sediment on the delta top, and faint foreset reflectors below the topset bed.
