The Edsall mine was an outer workings mine, this it looks just like a big pond. Its the only mine located in my homwetown of Hamburg NJ. Most of my neighbors and friends from the area have no idea that over 100 years ago, that "pond" was an active worksite, employing residents in the vicinity. Its located on a county road in Hamburg vicinity, the road actually bends around it, so I dont know which one came first, the mine, or the road.
