Three archives of the U. S. Geological Survey's Western Mineral Resources Team

The Western Mineral Resources Team of the U.S. Geological Survey (USGS) has three archives, which hold unpublished or difficult-to-obtain records and literature. The Technical Data Unit in Anchorage, Alaska, holds maps, field notes, and other records of the USGS work in Alaska. The USGS Field Office in Spokane, Washington, houses the more than 5,000 files from Federal government exploration programs that contracted to fund exploration for some commodities from 1950 until 1974. The Latin American Archive in Tucson, Arizona, holds material on Latin American mineral resources collected by the Center for Inter-American MineralResources Investigations.
