Figure 9. Side-scan sonar image of a moraine from Wells Embayment (modified from Miller, 1997). Erosion of the moraine has cut a notch on the lower side of the image. Nearby sand and gravel are derived from erosion of the moraine. Boulders are visible as white specks on the moraine, which shoals 5-10 meters above the surrounding bottom.
