The Black Pool Quartz Quarry in Chester. Veins of massive white quartz a few feet to 50 feet thick. Many of these veins have been prospected in the past, but the purpose of this prospecting is not known. The quartz must be iron free to prevent discoloration during weathering. Thank you to Tom Hoffman and Jim Moore for this treasure hunt. #hikethehilltowns with the #westernmasshilltownhikers #chesterma #hilltownhistory
