Is it possible to add distance scales and maybe a cross-section of the island showing Seven Site's elevation above sea level?
The island's dimensions are well known and easily measured with Google Earth. It's 80 meters from the castaway camp out to the beach. As for a cross-section, there is not much real topography on Niku. The place is basically flat. There are some sizable berms of coral thrown up along the NW coastline by storms and there's a low ridge that runs through the castaway camp. I've attached an aerial photo of the site with contour lines and also a key to the contour lines.
As you can see, assuming that the skull was buried near where it was found, it had rolled downhill from where the castaway died under the Ren tree (as confirmed by the dogs in 2017).
This might help those of us who haven't been there appreciate what visitors have to endure in order to move around and work (or survive).
Distances and contour lines don't adequately convey what it's like. It's no big deal to walk 80 meters across a mall parking lot. Covering the 80 meters from the Ren tree to the beach without a trail takes about 20 minutes. It took me two days to cut that trail in 2007.
The beach sand is soft and steeply sloped. Walking along the ocean beach is best done at low tide when you can walk on the firm sand at the water's edge.
