Since 1994, AZGS has participated in the STATEMAP component of the National Cooperative Geologic Mapping Program run by the USGS. AZGS puts matching funds for competitive federal money to map 1:24,000 quadrangles and compile 1:100,000 geologic maps.
Under the direction of Senior Geologist Jon Spencer, and guidance from the Arizona State Mapping Advisory Council, we have focused on maps in the Phoenix - Tucson corridor (blue quads in map at right). This year we are mapping in the Kingman, Prescott, and Yuma areas.
