Fremont Peak, a summit in central California’s Gabilan Range, has long been important for its commanding views over the Salinas Valley, Monterey Bay, and nearby inland routes. Known earlier as Gabilán or Gavilan Peak, it was renamed for John C. Frémont, who climbed it in 1846 with 60 armed surveyors to assess its military value. Ordered off by General José Castro, Frémont briefly built a crude stockade and raised a modified American flag before withdrawing without a fight. Later the peak became a site of commemoration, recreation, astronomy, and broadcasting, while its rocks preserve a much older geologic history along the Rocky Ridge fault.
