Zigzag boardwalk over coastal marsh, Greenfields, Western Australia

Black-and-white aerial view showing a long, angular boardwalk cutting across dense salt-marsh and tidal channels. The straight, geometric path bends in sharp angles and terminates at a small square viewing platform on the shoreline. Around the walkway are irregular ponds, meandering creeks and textured vegetation creating organic patterns; shallow water and a sandy tidal zone lie to the right. A stand of trees casts a dark shadow at the top edge, emphasizing the contrast between the human-made structure and the natural wetland forms.
