"There don’t seem to be any stories, from locals, of a huge construction project on the island. How did they construct those tunnels without anyone taking notes? Name of contractor? Drawings?"

Are there any photos of the island before Epstein bought it? Topography.

I'm thinking the tunnels were created first. The tennis court was created by clearing the "dirt" and building up the pedo hill.

How were pyramids built?

Now when someone buys a property, most neighbors expect construction/renovations to happen and they wouldn't pay much attention to some dudes moving dirt upwards...Rich people are eccentric and tend to do crazy things.

I'm surprised there are no windmills or solar panels.

The island apparently has a volcanic origin and is very likely to have been mined for tin, lead and other minerals associated with those two.

So we might have tunnels which pre-existed Epstein’s purchase.

1_Rain_Drop, you ask some good questions -- most of which I answered long ago, by doing "OHI" (OverHeadImagery) analysis -- covering the span of time from 2002 -- to last week's drone flights.

I'm putting together a time-sequence of the tunnel & underground room development that makes it very clear how things developed.

bitt, I said I wasn't going to publish my overall tunnel plan until it's ready -- but this D R A F T already explains a lot:

It still needs a LOT of work (i.e. the "tunnel network" needs to move down in the layer stack -- beneath the contour lines,etc...) I work on it as I have time not devoted to "critical path" items...

(ALL: This is still a rough DRAFT, Please DO NOT SHARE outside the Q thread!)

~~~~~~~~~~~

One of the critical (and most visible) aspects of digging tunnels is "spoil dirt" disposal. Instead of being obvious and piling it up like the Iranians (and other bad actors) do, Epstein's crew used it -- anywhere they needed construction dirt (roads, etc.)

(Yep, I've mapped the spoil disposal area on LSJI...)

BUT, 1_Rain_Drop et al, "Pedo Hill? wasn't "built up", per se... Look closely at the contour lines: that originally was a 148-foot tall, rounded-top hill, but E cut off the top -- and spread spoil dirt all across the flat "plateau" he'd made. Now the entire top of the hill is flat. Here's a BobCat making it so:

Until it was updated recently, GE's (Google Earth/Maps) "DEM (Digital Elevation Model) -- the elevation "grid" or "mesh" over which images are "draped" to give the terrain "3-D 'depth'" -- still thought that was a 148-foot tall, rounded-top hill. That meant anything flat (like a tennis court) was drawn curved (moreso if you had "elevation exaggeration" set high). Google corrected the elevation error in a recent database update...

BTW, the tunnels were built starting before 2002 -- but after luxurious houses, etc. were built...

There are no windmills, but there are big banks of solar cells...

Pyramids? I'm an archaeologist -- but, ya got me on how they relate to tunneling -- and trying to hide it... '-)

~~~~~~~~~~~

Hope this answered some of your questions...

P.S. Yeah, I know that I need to put the elevation labels on the contour lines -- It's on the list... '-)

P.P.S "BFB" labels tunnel access points -- typically covered by blue-painted metal boxes -- often where the tunnel boring machine started into the hillside "where the road ends"... (From Q's clue, "Bunker Forest Blue" in Qdrop #1007.).
