Figure 17. Detailed planar view of the large scour depression at the northern entrance to Plum Gut from the 4-meter digital terrain model (DTM) released in this report. Bathymetric data from this part of the DTM were originally collected during National Oceanic and Atmospheric Administration surveys H11445, H11446, and H11997. Note the presence of comet structures suggesting westward transport and the sand-wave fields. Location of view is shown in figure 12.
