Arizona Geology Map

The Arizona Geologic Survey has released an online version of the geologic map of Arizona. It uses a Google Maps interface, and allows you to zoom in on any area in the state to view the geologic units overlaid on a Google base map or satellite image. You can adjust the level of transparency of the map and view the unit descriptions as well. They have set the bar high for other geologic surveys! [Source: Arizona Geologic Survey via Geology.com.
