Figure 23. Detailed planar view of exposed glacial drift and the sand waves at the transition from shoal to channel from the DTM produced during NOAA survey H11079. Note that crest-line bifurcations are most common along the edge of a sand-wave field and that boulders are present on the exposed surface of the glacial drift. Location of view is shown in figure 22; depth key is shown in figure 20.
