Field Trip – FMI Sierrita Mine
Considering Arizona winter weather is perfect for a field day, don your hiking boots and join us for a field trip planned on Saturday, February 29th, 2020 to the Freeport McMoran Sierrita Mine near Green Valley, south of Tucson.
The Sierrita Mine has one of the largest proven copper reserves in the world, and has been worked for copper and molybdenum since 1907. We will be guided through the site by a representative of Freeport McMoran. It will be a great opportunity to ask questions and learn about how a large mine is operated and economically sustained!
Landslide Hazards: Anthem to Flagstaff
We are excited to announce a virtual meeting on October 21st, 2020 from 4-6pm. Our guest speakers will be Brian Gootee and Joe Cook, both of which are research geologists with the Arizona geological survey. Their topic will be “AZGS at Work for Arizona: Identifying Landslide Deposits and Hazards Along the I-17 Corridor from Anthem to Flagstaff, AZ”. This landslide series was focused on throughout the year by AEG, this will be a great opportunity to get a rich landslide history of the area as well as learn about the risks posed by landslides at present. The two guest speakers have a rich background in research pertaining to Arizona geologic hazards, where both have extensive research in Arizona earth fissures, debris flows, landslides and quaternary mapping. Bios for each speaker will be presented in subsequent emails. Speakers will present for around one hour, with a happy hour to follow.
If you did not follow the postings earlier in the year regarding the meeting topic, an excellent resource to get caught up is found at the AZGS blog postings found by clicking the link here. In summary, the findings of the AZGS regarding past landslides and current instability in the area from Anthem to Flagstaff is especially valuable with ADOT’s plans to spend over $300 million expanding and improving the I-17. There are significant risks posed by the landslides as some previous landslide planes cross the I-17. Future slides may block this highway, or could dam the Agua Fria River, threatening downstream communities with catastrophic flooding. More detailed information will follow.
AEG December Meeting 2020
We are lucky to have Dr. Brad Ross, the Director of the Geotechnical Center of Excellence (GCE) at the University of Arizona, and his team members presenting a webinar topic on Tuesday, December 15, 2020 at 5:30pm. The topic will be regarding the GCE’s effort to use thermal cameras to detect rockfall events and conditions, and the most recent training program that covers geotechnical radar monitoring systems. This will be an excellent opportunity to learn of this method, which is highly applicable to mining-related and rock stability geotechnical hazards. The webinar will be open to question and answer at the end of the talk.
Additionally, we plan to partake in some holiday festivities after the call! We will have a geology related game or two, and some prizes to give out. Looking forward to seeing you there!
