In 1967 and 1968 the USGS, in partnership with NASA and the National Park Service, extracted rock core from 13 locations in Yellowstone National Park. Depths of the holes ranged from 215 ft to 1,088 ft and the total drilled footage was 6,802 ft. The deepest hole was drilled in Norris Basin. Research on these cores provided critical understanding of complex geothermal systems that would inform the potential development of other systems, external to the park, as energy sources. These cores are extremely rare due to the many restrictions on sampling in the park. Years later, the cores were used to investigate the origin of some of Yellowstone supervolcano’s lavas using techniques that did not even exist when the cores...

The United States Geological Survey (USGS) collected a total of 179 samples of surficial sediment from abandoned mine wastepiles, ephemeral channels, nearby outcrops, and background areas representative of the undisturbed lithology within the Silver Island and Crater Island mining districts (Krahulec, 2018).The samples were sieved to obtain the less than 177 micron fraction. Geochemical analyses were completed through a third-party contract by SGS Laboratories. Samples were analyzed for 49 major, minor, and trace elements using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) methods (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe,...
