The pronounced northwest-southeast trending lineations in the center of the mapped area (B) die out to the north and appear buried by a coarse morphology that looks similar to the boulder and cobble areas seen at Boulder Reef and Gull Island Reef . The vertical exaggeration is 4x and the distance across the bottom of the image is about 3.5 km.
