Submarines still use it. Deepest Finger Lake.

And there are atleast two active salt mines on the south end in Watkins Glen and one salt mine in Himrod on east side that has been abandoned for 30ish years. It is a mystery why that salt mine closed suddenly in one day. Was sealed and everyone walked away. There are Rothschilds buried in a cemetery in Watkins Glen as well. Cornell College is on East side of Seneca. Who do we know that went to Cornell?

In your map across the lake do you see Willard? That used to be a psych center. Tunnels confirmed under it. Someone wrote a book about the stuff found in the suitcases in the attic of it. Hardly stuff “mentally ill” people would travel with. More like they were traveling and abducted. Then kept drugged and sexually abused is the local rumors. Also Seneca Army Depot is on that lake. It’s just above Willard. Also closed. There are white deer on the base. Funny how the base and psych center are right next to each other..
