I live on the south shore and have seen these trenches for decades. I never knew who or when they were dug or why they were there. Thanks for the education.

I appreciate the work, and none AI generated content. To see your face telling the story is valuable in an age of ai slop.

Absolutely fascinating! I lived in Nassau County back in the mid to late 80s and had no idea this existed

Fun fact, there used to be houses on the marshland. There still might be a handful left. But a while ago a law passed that houses claimed by nature couldn't be rebuilt. Some decades ago my father got a job to rebuilt one house destroyed by a fire started by some vandals.

As an airline pilot who frequently flies out of JFK I always thought they were for oyster farming or breaking up floods… guess I was wayyyyy off hahah

I flew over this on one of my many trips out of NYC I thought it was some odd natural thing like from glaciers or something!

I've been looking at these canals on local maps for decades now: at last I understand! <br>(Kind of ironic: if these were somethig beneficial, they probably would have filled-in years ago! That's just Murphy, hard at work!)

Stunned thinking first these were to be layout of street grids, then of the scope of these for all along more than half of the wholesouth shore or so, at the first time I could see aerial photos of these, as I browsed around NYC area. Sadly realized later that the wetlands were wrecked. Thanks, I did not know more of that history,
