Arizona Section Field Trip - November 9, 2019

AIPG AZ Section Field Trip with Arizona Geological Society - Earth Fissures

Field Trip Waiver Form

South-central Arizona is lacerated with hundreds of kilometers of earth fissures that have formed in the past 80 years. Voluminous groundwater withdrawal drives heterogeneous basin subsidence, which produces tension cracks that manifest as earth fissures along the basin perimeter or along bedrock highs. Southeastern Apache Junction, Maricopa County, and the Chandler Heights area, along the Maricopa – Pinal County line have been particularly hard hit; up to 5.7 m of subsidence has been documented in metropolitan Phoenix and Eloy (Pinal County). Fissures result from groundwater harvesting – up to 150 m decline in some areas. Earth fissures range from nascent ground cracks to wide-open fractures, tens of meters deep, meters wide, and hundreds of meters to kilometers in length. The transition from nascent ground crack to fissure gully is driven by rainfall events; fissure transverse to drainages capture runoff that erodes and widens the fissure. The Arizona Section of the American Institute of Professional Geologists and the Arizona Geological Society will be holding a joint field trip to examine some long-lived (decades) and recently reactivated fissures near Houston and Meridian Road, Apache Junction, and at the intersection of the Thompson and Hunt Highway adjacent to the Santan Mountains. The Houston Rd fissure provides an opportunity to examine a recent mitigation project (spring - summer 2018) that failed in the face of its first monsoon storm in Aug. 2018.


February 8, 2020 - AIPG Arizona Section Event - Tucson, Gem, Mineral & Fossil Showcase

Tucson becomes a playground for the world of international gem, mineral, fossils and meteorite aficionados annually during the Tucson Gem, Mineral & Fossil Showcase. The AIPG Arizona Section invites AIPG members, their families and friends to join us on Saturday, February 8, 2020 for a stroll through a small sampling of the more than 40 different shows followed by lunch. The cost of the buffet lunch is included in the registration fee for the event.

Our event will be on Saturday, February 8, 2020. We will meet in the lobby of the Travelodge Hotel and then break into small groups that will be led by a local geologist through the show held at the Desert Inn. Then we will walk to the Kettle Restaurant, where we’ll have lunch. The distance between the Travelodge and the restaurant is 0.2 miles. We don’t anticipate more than 2 hours of strolling through the exhibits. The Desert Inn show is open to the public and free.

We plan to have a private room at the restaurant so we may socialize and have a short presentation. After lunch, participants will be able to continue browsing the various shows.
