Geology

Sedgwick showcases a unique geologic history. The Little Pine Fault separates the relatively young eroded sediments and rolling hills of the Paso Robles formation from the sharply uplifted ancient rocks of the Franciscan Formation. This collection of rocks on the northeastern corner of the Reserve is a mélange of 150 million-year-old sea-floor rocks and organisms metamorphosed through the crushing pressure of the earth’s plates. Distinctive green serpentine outcroppings, deep rust-colored chert, and blueshist are beautiful examples of these rocks. The vegetation in this area is also unique, as the mineral composition of serpentine soils presents an inhospitable environment for many plants.
