I was wondering if anyone had been to these locations. They are absent from minedat.org. I have provided a link describing the locations and a map that possibly depicts Duell Hollow location, (East of Duell Hollow Rd., 2 mi. SE of Dover Station- now called Wingdale). I hope this plants the seed for exploration. The map is from a Quaker Hill history book that mentions Duell Hollow Mine, zoom in and look in NE shaded section. i worked for a lady who told me of the mine but got spooked when I started asking for the specifics. I think the Pawling Mine Might be just off Rt.55 ??? I have also stuimbled across reference to a mine on Quaker Hill possibly the Duell Hollow Mine??? There is a "Prospect Street" just east of 22 on Quaker Hill
