New Online Resource for Geologic Maps in Nevada


The Nevada Bureau of Mines and Geology has launched a new online resource for geologic maps that fall within Nevada: a searchable, interactive web map. This tool includes all geologic maps published by NBMG as well as numerous other Nevada maps published by other organizations such as the U.S. Geological Survey.

In addition to zooming in and out, panning around the map, and turning layers on and off, users can search by a variety of publication options including number, type, title, author, year, scale, county, and publisher. The search results are highlighted in the map view and are presented in a list that a user can scroll through and click for more information or link to the online resource for download.

This web map was compiled and designed by NBMG GIS team (Jennifer Vlcan, Katie Ryan, Rachel Micander, and Irene Seelye as well as past team members Selena Large and Matthew Richardson) and initiated from data included in NBMG Open-File Reports 2002-01 (Hess and Dennis) and 1997-02 (Klimowicz, Johnson, and Hess). This new resource supersedes NBMG Open-File Reports 2002-01 and 1997-02. Maps will be added to this web map on an ongoing basis.

The web map is available from the Maps & Data page on the NBMG website. The direct link to the application is The web map can be used on desktop and mobile devices and is cross platform (works with Apple, Windows, and Android). By default, only NBMG geologic maps are displayed, but users can turn on the “USGS and other organizations” layer to see additional maps.

We are interested in your experience using this new web map and want to continually improve and update this map. Please send feedback to
