Figure 7. Sidescan-sonar image with interpretation (top panel) and seismic-reflection profile (bottom panel) from the western part of Virgin Basin. The sidescan image shows the low-backscatter nature of the thick post-impoundment sediment deposit in this part of the lake. The sediment is onlapping alluvial deposits. The seismic profile shows the thickness of the post-impoundment sediment. The two images are correlated by seismic shot numbers. The numbers along the top of the seismic profile are shot numbers that correspond to the dots along the seismic tracklines in the top panel. See figure 1 for the location of this figure.
