A high quality deposit of dolomitic limestone was discovered here in 1862, but 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, which produced dolomite marble in several colors for use in terrazzo flooring, roofing, landscaping, and swimming pool and chemical filters. Premiere Marble was purchased by F.W. Aggregates in 1992 and continues operation to this day. It is the largest dolomite marble mine in the United States, and a recent survey found the deposit to be approximately seven miles long and 1,400 feet deep, indicating a virtually unlimited supply for many years to come.
