There are a number of flora and fauna present on Bernal Hill. Wildflowers include such species as the Yellow Mariposa Lily.[4]


Bernal Hill, along with the other hills in the San Francisco area, is a folded hill, created by the "wrinkling up" effect of the Pacific plate subducting under the North American plate, when the North American and Pacific plates were converging, around 150 million years ago. Near the summit you will find folded layers of very hard rock called radiolarian chert.[5] It is a sedimentary sillicate rock which gets its sillica content from the shells of microscopic creatures called radiolaria.The red color comes from iron oxide. In between the layers of chert are thinner layers of shale in many different colors from the same red as the surrounding rock to white, green and purple. Other types of rocks and minerals on the hill include serpeninite, jasper and clay.
