IGS interactive web map applications
The Idaho Geological Survey migrated interactive web map applications to the ESRI ArcGIS Online platform in 2023 to improve reliability of access to our services. New
features include support for mobile devices and the ability to cross-query data
between web maps.
The Idaho Geological Survey does not guarantee interactive web map application data to be free of errors nor assume liability for interpretations made from these data, or decisions based thereon.
Please see the Help document for general
information on using all web maps. The following web maps merit further

Full analytical data for samples selected through the
Geochem web map are only available as a CSV file download due to the number of
columns needed to ensure both human and machine readability.
Areas of historical and current mining activity can be
dangerous to investigate, and some hazards are not readily identifiable even
after careful observation. Mine sites may be on private property where entry is
prohibited by law. There are significant investments by the government and
other stakeholders to mitigate the danger to public safety and the environment
at some mine locations. Vandalizing gates constructed across mine openings or
other improvements may cause harm to others and result in prosecution.
