Precariously balanced rocks belong to a category of landform called "fragile geological features". Some exist due to erosion, such as rock arches or tower-like pinnacles. Places like Arches National Park in Utah hosts thousands of these features, where rainwater or freeze-thaw action has weathered sandstone to the point of imminent collapse. All of these features are striking to look at, but precarious boulders are particularly photogenic. While tourists tend to visit precarious boulders for selfies, seismologists admire these rocks for different reasons – because they can reveal earthquake activity during the deep past.

All large planets in our Solar System have rings and it has been suggested that Mars may have had a ring in the past. This raises the question of whether Earth also had a ring in the past. A team of international geoscientists recently examined the paleolatitudes of 21 asteroid impact craters from an anomalous ～40 m.y. period of enhanced meteor impact cratering known as the Ordovician impact spike and found that all craters fall in an equatorial band at ≤30°, despite ～70 % of exposed, potentially crater-preserving crust lying outside this band.

November marks the 50th anniversary of the discovery of the Australopithecus afarensis skeleton “Lucy.” She is referenced in the #GSABulletin article “Paleoenvironments of the earliest stone toolmakers, Gona, Ethiopia,” by Jay Quade and colleagues, at https://lnkd.in/gbpgpspf. #Paleontology #Ethiopia #Paleoanthropology #GSAPubs University of Arizona Geosciences Case Western Reserve University School of Medicine Photo from the paleontological collections of the National Museum of Ethiopia, CC-BY-NC.

Gray et al. use pIR-IRSL, carbonate U-Th series, and zircon SHRIMP U-Th series geochronology to help resolve the timing, duration, and origin of the Chemehuevi Formation in the Lower Colorado River corridor, research that can help further our understanding of continental-scale river systems. https://lnkd.in/gv2h8BqU #ColoradoRiver #Geochronology #Geomorphology #QuaternaryGeology #GSABulletin #OpenAccess #GSAPubs P.

I'm looking forward to working with colleagues at the Geological Society of America and our partners at the Geological Society of Africa to host this webinar about geothermal energy. #EnergyTransition #GeothermalEnergy #Webinar #SustainableEnergy #GSA #GSAf

Today is GIS Day! This year’s theme – Mapping Minds, Shaping the World – highlights how geographic information system (GIS) technology has changed the way we understand, navigate and shape our world. Together, human creativity and technology help us discover hidden trends, spur sustainable growth and make smarter decisions.

Check out MHC GEO Club's logo on Geological Society of America's Geology Club T-Shirt! Last year's tournament was a lot of fun-- we got to collaborate with campus partners and interact with other Geology Clubs across the country. With the funding from the Tee-Off, we were able to support students to GSA Connects and other miscellaneous events. Please consider buying a t-shirt to raise awareness for Geology Clubs and funds for Geo Club Support everywhere :)

Geological Society of America's support for Geology Clubs across the country made a huge impact for us at Mount Holyoke College during the 2024 GSA Geology Club Tee Off when we walked away with second place, and 1500 dollars of prize money! Those funds went directly to student members, who got to attend #GSAConnects2024 solely because of the money won through this bracket tournament. If you want to rock a stylish tee shirt, represent MHC, and keep supporting clubs like ours, I strongly encourage you to buy one of these tees!
