I was curious about the Epstein-Island but did not trust GOOG Maps to much. So I used Apple Maps to investigate it a bit. The pictures from Apple maps seem older (some parts are missing e.g. the top of the temple, the tennis court,…)
But I found some really interesting things that could lead to the underground tunnel(s). Also I found something, that could relate to an other Q-Post (Bunker.Forest.Blue.) - but it also could be nothing.
