In 1862, this high quality deposit of dolomitic limestone was discovered in the Inyo Mountains east of Lone Pine and north of Owens Lake near the town of Swansea. Its remote location delayed development until 1883, when the Carson & Colorado Railroad was constructed. In 1885, Drew Haven Dunn filed a mining claim and the Inyo Marble Company began quarrying operations. The property was purchased in 1959 by Premiere Marble Products. They produced dolomite marble in several colors and its final product is widely used in terrazzo flooring, roofing, landscaping and chemical filters.
These some of the photos of what is left. Thanks to photos by Josh Patterson
