WAC image showing a side view of the Serqet and Nut regions. Serqet is mainly composed of ridge, which separates it and other region on the distal part of the lobe from the inner regions toward the neck, and a smooth flat plain that forms the rim of the Nut depression. b) NAC image highlighting the morphological features. Note that both Serqet and Nut are covered by patches of Ma’at debris, which is occasionally striated. In addition, the part of Nut region adjacent to Serqet plain material is covered by boulders and talus that may have formed through the erosion of the Serqet region. Arrows point to locations of the boundary between Nut and Serqet as well as its surroundings.
