On 3 August we [AZGS] debuted our new Online Publications page. There are about 50 geologic reports and maps there now as free downloadable PDFs -- with dozens more to come soon.
*New Publication Model - The AZGS Online Publication Outlet.* AZGS is migrating to a digital publication model, making new publications available free online. And for the first time, we’re marketing GIS data of newly released geologic quadrangles: geodatebase, shapefiles, for $25.00. Printed maps still available at the AZGS Map and Bookstore.
