That’s dubious! It’s an island...at what level below the ground do you think the water table is?

59 ft. allows for a lot of underground tunnels.

Shhh... don’t try to use logic. The tunnels are there! Just like the tunnels under the McMartin preschool and Comet Pizza! If everyone just believes in them hard enough, and claps their hands, the tunnels will appear!

Here is one tunnel from drone footage. Photo's and vidoe of the island are not hard to find. You will even find some concrete work being done that another poster mentioned, too.
