- Gold mining production staged to perform well in 2018 with production at the Copperstone and Moss Mines of western Arizona.
- Oddly enough, Arizona has an earth fissure season; a season when fissures are more likely to first appear or undergo renewed activity. This article showcases revised earth fissure maps for parts of Cochise, Maricopa, and Pinal Counties, as well as case studies of one new (Tator Hills) and one reactivated fissure (Apache Junction). Systematic mapping and observations of the physical conditions of ‘older’ fissures suggests that earth fissure activity in some study areas is waning.
- Utah Geological Survey (UGS) and the University of Utah Seismograph Stations (UUSS) release a 1:500,000 scale ‘Utah Earthquakes (1850-2016) and Quaternary Faults’ map.
- Arizona State University (ASU) is partnering with Phoenix-area libraries to develop field-tested, replicable, low-cost toolkits of citizen science resources for public libraries.
- One Paleontologist's / Data Scientist's Experience at the Geological Society of America's 2017 Annual MeetingI would say that GSA is probably the most important annual meeting for an American paleontologist. Although there are other meetings more specifically tailored to paleontology, the turnout is generally the best at GSA
- On 28 Sept. 2017, I drove to Hayden to interview long-time ASARCO employee Joe Wilhelm regarding the history and future of the Hayden Smelter.
On the evening of 1 Nov. 2015, residents of the Phoenix Metro area were rudely awakened when a magnitude 4.1 earthquake shook the valley. According to the Arizona Republic, and numerous other Phoenix-based media outlets, people across the Valley of the Sun felt a sharp jolt followed by several seconds of ground shaking. There were no reports of injuries or damage. That modest earthquake generated the sort of media attention that might normally accompany a punishing magnitude 5 or 6 earthquake. But as with real estate sales, it’s all about location.
- Following a 15-month hiatus, the Arizona Mining Review (AMR) filmed and its 40th episode, Pozzolan mining in central Arizona, on 28 Aug 2017.
- In 1937, geologist Eldred Dewey Wilson coined the phrase ‘Mazatzal Revolution’ to describe mountain building along the western edge of the North American craton.
By Order dated July 13, 2017, Maricopa County Superior Court Judge Mark H. Brain (presiding judge in the Gila River adjudication) affirmed the most recent effort by the Arizona Dept. of Water Resources (ADWR) to delineate the lateral extent of certain hydrogeologic areas known as subflow zones in the San Pedro River watershed in southeastern Arizona. A well located within a subflow zone is presumed to be pumping subflow, which is water that is hydraulically connected to the surface flow of a perennial or intermittent stream.
- The US Geological Survey just released an online interactive map tool that showcases earthquake event scenarios for select faults in the contiguous U.S.
