The Tucson Weekly for Sept 27 has 3 full pages dedicated to earth fissures and in particular, their potential to serve as conduits to ground water. See the full story by Sam Stoker at http://www.tucsonweekly.com/gbase/Currents/Content?oid=oid:101037.
This is their annual "best of..." issue which means it's widely read, but also snapped up from the newstands quickly.
