The Linwood Mine in Scott County, Iowa, operating continuously since 1944, is a massive underground limestone operation situated within Paleozoic sedimentary strata along the Mississippi River. While primarily developed for high-grade aggregate and industrial lime production, the mine has gained renown among mineral collectors for distinct cavity-filling specimens. Miners and collectors have retrieved exceptional barite crystals from these vugs and solution openings. The barite from this locality typically occurs as transparent to translucent clusters, often prized for their complex habit, high luster, and unique etched or solution-rounded surfaces.
