Serving the Nation and Rockhounds for 140 Years
In 1881, Nevada’s Comstock Lode was the among the first USGS mining-district surveys.

Many people, rockhounds and prospectors among them, rely on information from topographical maps, geological reports, and mining-district surveys.

Many also go on-line to check the magnitude of recent earthquakes, monitor current volcanic activity, or keep up with new developments in the Earth sciences. Much of this readily accessible, accurate information is compiled and made available by the United States Geological Survey (USGS). The USGS, familiarly known as the “Survey,” is the scientific agency of the U. S. Department of the Interior.When the Survey was established in 1879, much of the nation, especially the West, was unmapped and most of its mineral resources were yet undiscovered. Accordingly, the Survey’s initial work focused on mapping and mineral surveying.

The Survey’s interests have since broadened greatly with the advancement of science and the changing needs of the nation.Over 140 years, the USGS has presented the results of its Theld surveys and laboratory research in many thousands of reports, papers, and maps, making them available to the public free of charge or at a nominal cost.How all this information was compiled—and is still being compiled today—is a fascinating story. In the early 1800s, the federal government had little interest in mapping and investigating the geology of its vast public lands.The few surveys of that era had been performed by the states or private interests, usually to support regional agricultural, military, or transportation projects.
