AZGS Online Map and Database Services
The Arizona Geological Survey provides a number of online and interactive map and database resources focusing on geology, mineral resources and natural hazards. To view these data, select the appropriate map or database service from the list below.
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.
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.
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.
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.
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.
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.
