Maps

Fundamental Science Practices

USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.

Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

Map showing high-purity quartzite in California, Nevada, Utah, Idaho, and Montana Map showing high-purity quartzite in California, Nevada, Utah, Idaho, and Montana

Unusually pure quartzite of Ordovician age crops out in hundreds of places from Owens River, California to southwestern Montana. It constitutes a single lithologic type that is called the Kinnikinic Quartzite in central Idaho, the Swan Peak Quartzite in southeastern Idaho and adjacent parts of Utah, and the Eureka Quartizite in western Utah, Nevada, and southern California.
