[Rockhounds] AD - Garza mineral list - July 2019 & update

[Alan Goldstein]

I had a conversation with Steve Garza about his favorite collecting sites in New England. I thought it might be some of the pegmatites in Maine, but none made the final "list" even though he has a lot of material from Mt Mica, Harvard Quarry, Nevel Quarry, and the Dunton Gem Quarry. Steve said the Conklin Quarry in Rhode Island and the I-495/295 interchange road cuts (during construction) in Marlboro, Massachusetts were his favorites because the deposits were so interesting and had unusual minerals.
