Based on 28 May 2026 field observations and calibrated survey photographs. The corrected camera alignment and rebuilt surface were reviewed before this tour was remade. H5 alternates photographic texture with an illustrative clay view of exactly the same surface; raking light and ambient occlusion emphasize relief without adding geological boundaries. Constructional relief, erosion, rockfall and cementation remain competing explanations for the gullies. No age or sea-level elevation is assigned. Individual coral and giant-clam observations have not all been located as precise model targets. Vegetation, moving water and incomplete coverage remain uncertain; two small uncertain bare-surface patches in the full model are outside this display crop. Grey cut walls, backing, support and reveal are artificial presentation geometry.
