I actually tried panning there a while ago- got a little lead shot. From what I've read, most gold in NY is microscopic if it exists at all. Mining investment scams were all the rage in the 1800's. That being said, since any gold in NY belongs to the state; A mining operation might have sold ore for worthless arsenic, that just happened to have a hefty gold by prod- just speculation. Those pits are just below the road to the tower. It does sound like there is other stuff more toward pine pond on the other side of the street- I think jackstraw may have seen this?
I want to find gold in the hudson valley as proof of concept. There is a guy on youtube who does well in Vermont, Yankee gold prospecting new england.
Here is a NY Times article about a NY gold find that probably never "panned" out.
