Geoscience in Your State: Nevada

Interactive database for geologic maps of the United States

The U.S. Geological Survey hosts the National Geologic Map Database (NGMDB). This interactive tool serves as a national archive for high-quality, standardized geologic maps created by the U.S. Geological Survey and state geological surveys.

The MapView section of the NGMDB displays geologic maps from across the country dating back to 1879. The database is searchable by address, and results can be narrowed further using scale and date filters.

Interactive database for topographic maps of the United States

The U.S. Geological Survey hosts topoView, an interactive database of the survey’s topographic maps.

The map is searchable by address, and clicking on any point on the map brings up topographic maps of the area dating back to 1879. Map results can be narrowed further using scale and date filters.

Clicking the “show” option will overlay the selected map onto the coordinates of topoView’s base map. Adjusting the map overlay transparency allows comparison of historical and present-day topography.

All maps in topoView are downloadable in multiple formats.

House passes legislation to advance nuclear waste storage in New Mexico and Nevada

Nuclear power plant, Czech Republic

On May 10, the House passed the Nuclear Waste Policy Amendments Act of 2018 (H.R. 3053). The bill would resume and expedite licensing for the proposed Yucca Mountain nuclear waste repository and authorize the Department of Energy (DOE) to construct an interim storage facility for consolidation and temporary storage of nuclear waste in New Mexico until the completion of a permanent facility. The FY 2019 Senate Energy and Water Development Appropriations bill (S. 2975) does not include funding for Yucca Mountain storage, but the House bill (H.R. 5895) would provide $268 million to restart the adjudication of the Yucca Mountain license application.

Interactive map of groundwater monitoring information in the United States

The National Ground-Water Monitoring Network compiles information from over 7,000 groundwater monitoring wells across the country, including Federal, State, and local groundwater monitoring networks. Although the image above only shows the contiguous United States, the interactive map also includes wells from Alaska, Hawaii, Puerto Rico, Guam, and the U.S. Virgin Islands.

Interactive map of post-fire debris-flow hazards in the Western United States

The U.S. Geological Survey conducts post-fire debris-flow hazard assessments for many major fires across the Western United States. The information from these assessments is provided in an interactive map, allowing users to view fires by location or name and access detailed maps of debris-flow probability in the area affected by each fire. Users can select fires by year back to 2013.

Water as One Resource

This course provides an overview of how groundwater and surface water interact, what the implications of these interactions on water resources are, and how water can be more effectively managed if an understanding of these interactions is incorporated.

The course presenters are Ken Bradbury from the Wisconsin Geological and Natural History Survey, William A. Alley from the National Groundwater Association, and Thomas Harter from the University of California, Davis.
