Included are historical maps and publications of USGS, as well as early publications of many federal, state and other geological surveys. Records of select geological societies are also maintained in the collection, such as the Geological Society of Washington, which was founded by John Wesley Powell and other noted scientists after the Civil ...
Well logging, also known as borehole logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole.The log may be based either on visual inspection of samples brought to the surface (geological logs) or on physical measurements made by instruments lowered into the hole (geophysical logs).

The Core Research Center is a facility run by the United States Geological Survey, located in "F" bay in building 810 on the Denver Federal Center campus. It is maintained by the USGS to preserve valuable rock cores, well cuttings and various other geologic samples for use by scientists and educators from government, industry and academia.

Seismic, well logs and other input data are each represented as a probability density function (PDF), which provides a geostatistical description based on histograms and variograms. Together these define the chances of a particular value at a particular location, and the expected geological scale and composition throughout the modeled area.
The Board on Geographic Names database was a record of investigative work of the USGS Board on Geographic Names' Domestic Names Committee, and decisions that it had made from 1890 onwards, as well as names that were enshrined by Acts of Congress. [28] Elevation and location data followed the same rules as for the NGNDB. [29]
