Figure 14. Detailed view of sidescan-sonar imagery and corresponding hill-shaded bathymetry showing tabular erosional outliers. Curvilinear shadows in the sidescan-sonar imagery correspond to the outline of small plateaus in the bathymetry. Boulders are visible in both images, on the sidescan-sonar imagery as light-toned targets with dark shadows and within the bathymetry as dark targets. The area of boulders in the lower right corner of both images shows an exposure of till. Lighter backscatter between the erosional outliers is from coarse-grained, bouldery sediment. Images are in UTM. Location of figure shown in figure 2 .
