Map Services

Arizona Oil & Gas Well Viewer

Our newest interactive map service, published in October 2013, displays 1,100 wells, including wells drilled for oil & gas and geothermal exploration. Digital well logs and, in some cases, log ASCII standard (LAS) digital data accompany each well. 

Gold King Mine Map

Interactive map of Gold King Mine water sampling in CO, NM, UT and AZ. The map displays 115 sample sites in Colorado, nearly 80 in New Mexico, 20 in Utah, and 5 sample sites in Arizona.

Earth Fissure Viewer

Shows the distribution of mapped earth fissures in Cochise, Maricopa and Pinal Counties. Also, provides links to 24 published earth fissure study area maps.

Earth Fissure Viewer for Google Earth

The distribution of mapped earth fissures in Cochise, Maricopa and Pinal Counties in Google Earth (.kmz file) environment.

Holbrook Basin Potash Deposit

The Colorado Plateau east of Holbrook is underlain by a potash deposit estimated by the AZGS to contain between 682 million and 2.27 billion metric tons of the mineral. This map shows drilled and permitted drill holes and includes an isopach map showing potash thickness.

Interactive Geologic Map of Grand Canyon, Arizona

Work in progress displaying the geology of Grand Canyon. Mapping largely by George Billingsley and his colleagues at the U.S. Geological Survey. Ryan Clark, formally of the Arizona Geological Survey, built this interactive map and provided permission to showcase it here.

Mines of Arizona

Locations, status, primary and secondary commodities. Courtesy of the US Geological Survey's Mineral Resources database. Link opens a Google Earth (.kmz) file.

Natural Hazards in Arizona

Natural hazards viewer showcasing earth fissures, active faults and earthquakes, flood potential and fire risk index. Includes a “Find local hazards” search tool.

Seismic Stations in Arizona

Explore Arizona earthquake activity in near real-time using the Arizona Broadband Seismic Network.

Database Services

AZGS Document Repository

Geologic reports, bulletins and maps published by AZGS and its predecessors agencies from 1915 to the present. All products are available free in PDF format.


The U.S. Geoscience Information Network (USGIN) exposes, connects, and opens earth science data. USGIN is a federated information-sharing framework that uses free and open-source technology, capable of interacting with similarly configured data-sharing networks.

National Geothermal Data System (NGDS)

NGDS is a distributed data system providing access to information resources related to geothermal energy. Data contributors include academic researchers, private industry, and state and federal agencies.

Arizona Geological Survey Mining Data

AZGS Mining Data hosts 1000s of historic Arizona mine files, photographs, and maps from the collection of the former AZ Department of Mines and Mineral Resources. Search by mine name or use the map search tool.


Online Bibliography of Arizona Geology (AZGeoBib) comprises more than 13,000 citations of geologic studies from throughout Arizona. The citation record goes back to A.D. 1848

Geologic Story Map

Geologist in Grand Canyon

Join AZGS geologist Steve Rauzi and a team of Conoco geoscientists as they raft through Grand Canyon examining the Precambrian Chuar Group. The trip, which occurred in 1996, begins at Lees Ferry and ends at river-mile 225.

Arizona's San Pedro River

The San Pedro River is Arizona's last undammed river. This 122-mile map story from the US-Mexico Frontier to Winkelman, Arizona, shows the San Pedro River Valley as seen through the eyes of a geologist, AZGS's Joe Cook.

Geologic Tour of GC's South Kaibab Trail

Join Dr. Dale Nations, Emeritus Regents Professor at Northern Arizona University, and his students as they descend from the South Rim along the South Kaibab Trail to Phantom Ranch on the Canyon floor.
