Nevada is a unique state whose opportunities and challenges stem from its distinctive geologic, geographic, economic, and demographic heritages. It is richly endowed in natural resources but is also prone to earthquakes, floods, and other natural hazards. The Nevada Bureau of Mines and Geology (NBMG) is the state geological survey of Nevada and is tasked with analyzing and characterizing these resources and hazards for the benefit of Nevada’s citizens.
As defined by state statutes, NBMG serves as the state’s official locus of data, analysis, and exchange on Nevada’s geology, natural resources, and geologic hazards. We disseminate this information to local, state, and federal agencies, major industries, engineers, educators, and to the general public. Our primary mission is to provide geologic information to enhance the safety of Nevada’s citizens and to facilitate environmentally sound and sustainable economic development of Nevada’s mineral and energy resources, applying geologic research for the public good throughout the state. We are a statewide public service unit that resides in the Mackay School of Earth Sciences and Engineering in the College of Science at the University of Nevada, Reno (UNR). Since its inception in 1929, NBMG has produced geologic maps for much of the state and catalogued more than 320,000 geologic specimens and reports. This report summarizes NBMG activities, programs, and accomplishments for 2016 and 2017.
To fulfill its mandate, NBMG employs about 28 individuals, including geoscientists, GIS (geographic information systems) and cartographic professionals, technicians, and staff. NBMG conducts research and publishes reports on mineral, geothermal, and oil and gas resources, engineering geology, geologic hazards, hydrogeology, geologic mapping, and Nevada’s overall geologic framework. NBMG cooperates with numerous state and federal agencies in conducting this research and in providing geologic and resource information. Research results are published as NBMG bulletins, reports, maps, and special publications, as well as in federal publications and scientific journals. In the 2016–2017 period, NBMG produced dozens of publications on Nevada’s geology, natural resources, and geologic hazards, including 15 NBMG geologic maps, 11 NBMG reports and other publications, and more than 75 papers in nationally and internationally recognized scientific journals. Geologic research conducted by NBMG has benefited many industries in Nevada (e.g., the gold, lithium, silver, copper, and geothermal industries) and enabled the state to become leading producers of gold and geothermal power. Geologic information managed by NBMG also helps government officials make informed decisions on the use of Nevada’s lands. To preserve and provide public access to this information, NBMG manages and operates the Great Basin Science Sample and Records Library (GBSSRL), whose staff catalogues and archives geologic reports, rock and mineral samples (including cuttings and core from geothermal and oil-gas wells), mining district files, aerial photographs, and geologic and topographic maps. About half of the NBMG staff are supported by State funding, with the other half supported by external grants. NBMG has been very successful in acquiring external grants and expended ~$3.36M in external funds on statewide projects in fiscal years 2016 and 2017.
Continued rapid population growth in Nevada has resulted in increasing needs for mineral, energy, and groundwater resources, land-use and infrastructure planning, and assessments of geologic hazards. NBMG’s major programs are geared toward applying the forefront of technology to satisfy these needs. NBMG’s major activities are described in the following chapters of this report: 1) Geologic Mapping; 2) Mineral Resources; 3) Geothermal Resources; 4) Tectonic Setting; 5) Geologic Hazards; 6) Data Dissemination; and 7) Education and Outreach.
This report was prepared for the Board of Regents of the Nevada System of Higher Education.

A message from Rich Koehler, NBMG: The lidar data set NBMG was instrumental in acquiring through the USGS 3DEP program is featured in an article in ArcUser magazine. It highlights how our local municipality is using the data and encourages other cities to get involved with the 3DEP program.
Excerpts from article: “Turning a terabyte (TB) of lidar data into ready-to-use GIS products can be quite challenging. In this article, I share the strategies I used to transform lidar data into GIS products to benefit Washoe County, Nevada.”
“In 2017, the United States Geological Survey (USGS) 3D Elevation Program (3DEP), in cooperation with the Nevada Bureau of Mines and Geology (NBMG) and local cooperators, flew a lidar mission to collect quality level 1 (QL1) and quality level 2 (QL2) LAS data across more than 1,500 square miles covering Reno, Sparks, Carson City, and surrounding areas in northern Nevada. Local cooperators included the Washoe County Regional Basemap Committee (Washoe County, City of Reno, City of Sparks, and NV Energy), US Forest Service, Lyon County, and Storey County.
Here are a few articles sent in previous NBMG emails that explain the background of the lidar acquisition project and data that is now publicly available.

Below the Neon: Reno’s Bare Earth
Recent Reno–Sparks–Carson City Lidar Acquisition Project
Story maps provide an excellent means for NBMG staff to share information about programs and activities throughout Nevada with the public. NBMG Cartography and GIS group members Irene Seelye and Rachel Micander have created a story map documenting the recent lidar acquisition in the greater Reno–Sparks–Carson City area. This story map, titled “Reno’s Bare Earth: Below the Neon,” documents the differences between various quality levels of lidar data, air photos, and the bare earth data that are obtained with lidar. This recent lidar acquisition was made possible with matching funds from the Office of the Vice President of Research and Innovation at the University of Nevada, Reno and through partnerships with the Washoe Regional Basemap Committee, the US Forest Service, Lyon County, and Storey County.

[May 24, 2019] New Paper! Drought-Triggered Inflation and Earthquakes at Long Valley Caldera
“In a new study we have explored how recent drought periods in California influence the timing of Long Valley active caldera inflation near the city of Mammoth, California. The study uses GPS and seismic data to show how uplift of the Sierra Nevada and magmatic inflation at Long Valley accelerated when the drought initiated in late 2011. The subsequent inflation changed the distribution of active tectonic strain rates in the adjacent central Walker Lane, east of the Sierra Nevada, effecting seismicity rates. Earthquakes occurred more frequently in places where the geodetic strain rates increased, suggesting that hydrological surface loading (e.g. from changing levels of aquifers, snow and lakes) affects the magmatic system in ways that subsequently influence earthquake occurrence. The study captures in new detail the complex links between climate, active volcanoes and earthquakes in eastern California and Nevada.
The work is a collaboration between the Nevada Bureau of Mines and Geology and Department of Mathematics and Statistics in the UNR College of Science. The study appears as a new accepted article in the Journal of Geophysical Research – Solid Earth.”
