I took the oppurtunity on the first day that the Sterling Hill Mine was opened to go digging in the Passaic and Noble Pits, and dig through the mine run dump. The Passic/Noble pits are only open to collectors on the last Sunday of the month. It was still very cold and partially covered with snow, and this limited the finds somewhat. The mine run dump had some interesting Fluorite and Galena that was dumped from Lime Crest Quarry, and also had a bunch of dumped Agates from worldwide localities.
