After more than 20 years of research, Sonoma State University geology professor David Bero has published detailed maps of Ring Mountain and the Tiburon Peninsula. He presented these new maps as the featured speaker of the SSU Geology Club's lecture series on February 19.
Geologists around the world are known for their love of the outdoors, and Bero, who has been lecturing at Sonoma State for the past eight years, is no exception. He has spent nearly every weekend during the past 20 years hiking the trails and enjoying the sweeping vistas of his native Marin County. But unlike day hikers gazing at the panoramic ocean views, Bero's focus is on the rocks beneath him.
