Known formerly as the Society of Economic Paleontologists and Mineralogists, the SEPM acronym remains, and the new shortened name, Society for Sedimentary Geology, still reflects a mission of and dedication to disseminating information on sedimentology, stratigraphy, paleontology, hydrogeology, subsurface exploration, sedimentary tectonics, and geologic disasters of the terrestrial and marine realms.


SEPM is subdivided into eight regional sections in North  America. The Pacific Section SEPM, based in southern California, is one of the premier geological societies of western North America. It encompasses the Pacific states: California, Oregon, Washington, Alaska, and Hawaii, and overlaps with the Rocky Mountain Section SEPM in parts of the Arizona and Nevada.

Eric Hendrix - In Memoriam

PSSEPM has lost a long time supporter, contributor, and friend. It is with a heavy heart that we announce the passing of Eric Hendrix  on October 10, 2019. Eric was a senior consultant for Earth Consultants in Santa Ana and a strong supporter of students and the geosciences. 


"Eric was a great guy, always contributing positive energy to the group! I really enjoyed working with him and was amazed about his extensive knowledge on California geology, whether it was sedimentology, tectonics, structural geology, or his main expertise, hydrogeology. I had many great conversations on the Monterey Formation with him and he shared a lot of his books with me that helped me during my times as a student" – Yannick Wirtz


"Eric was a really warm, big-hearted guy and a heck of a good geologist. I think that all of us benefited from knowing him. My connections with him were primarily through the Pacific Section SEPM where he was a long-time, strong and reliable contributor and colleague." – Rick Behl


"Eric had a big heart and he cared deeply for PS-SEPM." -  Mario Caputo

Rest in Peace, Eric. You will be missed
