USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.
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 the oxygen isotope composition of granitoid rocks of the Basin-Range province Map showing the oxygen isotope composition of granitoid rocks of the Basin-Range province
This map presents oxygen suite of granitoid rocks from Province of Nevada, Utah, isotope data for a the Basin and Range California, and Arizona. Two random samples were collected each of two randomly selected plutons within 1° x 1° area. For this study, only the m.nnbered sample was analyzed except in instance when sample GR-128 was substituted its odd-numbered counterpart (CR-127)...
Map showing vegetation distribution in the central part of the East Tintic Mountains, Utah Map showing vegetation distribution in the central part of the East Tintic Mountains, Utah
With the development of remote sensing technology has come the capability of defining and mapping plant communities by means of their spectral properties. Such maps will be an important aid in resource evaluation and management, especially in densely vegetated and remote areas of the world. This study in part of a broader program to determine the usefulness of multispectral scanner...
Maps showing aeromagnetic survey and geologic interpretation of the Chignik and Sutwik Island quadrangles, Alaska Maps showing aeromagnetic survey and geologic interpretation of the Chignik and Sutwik Island quadrangles, Alaska
An aeromagnetic survey over part of the Chignik and Sutwik Island quadrangles, on the southern Alaska Peninsula, was flown in 1977 as part of the Alaska mineral resource assessment program (AMRAP). Maps at scales 1:250,000 and 1:63,360 have been released on open-file (U.s. Geological Survey, 1978a, 1978b). This report includes the aeromagnetic map superimposed on the topographic base...
