Thanks for doing something I should've done myself. Popping out to Google Maps gives a higher resolution view of the island and with that one can easily pick out a network of trails around the island though I haven't seen clear indications of settlements yet. I think you can even see on the east side of the island at least one man-made fish trap similar to those found in other parts of the world.
It's clear that they travel all over the island making use of the resources available. I wonder whether anyone has reported seeing them swim. Some of the trails lead to small inlets and across to small islets on the perimeter which are now isolated from the main island.
Anyway, thanks for this post. It enhances the comment above.
According to the book that I have been reading that was linked in a reply that has since been deleted, North Sentinel Island is relatively flat and has a coral base, unlike the other Andaman Islands which are remnants of an eroded and submerged island chain that existed offshore of Burma, Thailand, etc.
The vegetation also is different in that the trees are very tall and the canopy restricts light to the extent that there is not as much undergrowth on NSI as on neighboring islands so it is likely that any structures they build from the available wood are concealed under the forest canopy.
There are quite a few trails visible on Google Earth and each tails out in the forest not far off of the beaches though some are visible in areas noted on the maps as being marshes. Very interesting place but from the history documented in the book, it is pretty clear that the inhabitants wish to be left alone and that contact with outsiders has caused them and natives on neighboring islands much hardship since first contact several centuries ago.
One noteworthy thing is that it is simply not accurate to characterize them as uncontacted. It is better to describe them as isolated and vulnerable and therefore worthy of any protections we can offer even if that means to leave them to their own devices.
The book was written after the great Christmas quake and tsunami in 2004 and is partially available thru the wayback machine. [0] There's a lot to take in and some chapters don't exist there but it is a deep rabbit hole to tumble into. Very interesting stuff with a nice accounting of historical contacts with people on many of the islands out there.
