The Bruin Geological Survey (BGS) is a UCLA Student Organization dedicated to running fun and informative fieldtrips, on which members can see great geology first-hand, as well as education and outreach events, at which members can share their knowledge of our Earth with others.

The BGS is open to all UCLA students, graduate and undergraduate, regardless of major (no prior knowledge of geology is necessary!). Faculty, staff and alumni are welcome to join our trips as well. To join the BGS, simply email us at bgs.ucla@gmail.com. To attend one of our upcoming trips, just RSVP to bgs.ucla@gmail.com by the "RSVP by" date listed in the event description. You can also contact us on our Facebook page. https://www.facebook.com/bruingeologicalsurvey

We hope you'll join us for some good fun, time outdoors and, of course, great geology on one of our upcoming trips!


Meet the Board Members

  Casey Yamamoto - President   4th Year Engineering Geology B.S. student  Casey first became interested in geology after visiting the Black Hills of South Dakota, where she saw hillsides sparkling with muscovite mica. She has worked on a research project studying the Paleocene-Eocene Thermal Maximum under Professor Aradhna Tripati and currently she is studying the crustal thickening history of Southern Tibet under Professor Mark Harrison. In her free time, she enjoys hiking and alpine climbing.
