A manganese deposit of Pleistocene age in Bannock County, Idaho
Reports of the discovery and exploration of manganese deposits in southeastern Idaho within recent years having come to the Geological Survey, the writer took advantage of an opportunity to spend a day at the deposits in October, 1926. The examination was made in company with V. C. Heikes, of the Bureau of Mines. The local operators, especially Mr. George L. Smith, of the Idaho Manganese Co., courteously gave assistance during the visit.
