Norfolk Tug’s George Holland has been making regular trips up the North River with a hopper barge this summer, heading for the quarry in Clinton Point near Poughkeepsie where they collect crushed stone for delivery to distribution points around the metropolitan area and return back down the river. These pictures were taken on Sunday of Labor Day weekend and, less than a week later, George has just completed another round trip, delivering their cargo I believe based on what I can see on AIS to New York Sand and Stone by the Brooklyn Navy Yard. The Clinton Point quarry has been in operation for over 100 years and dolomite rock from there is probably embedded in most structures we see in the region.
