AZGS launched the new Earth Fissure Viewer today as an online, interactive map tool that displays over 330 miles of Earth fissures mapped by our geologists in Maricopa, Pima, Pinal, and Cochise counties.
The new version is faster and easier to navigate, with increased functionality. You can easily zoom into any of the mapped study areas and see streets or sections. The maps are all downloadable in pdf format.
