 Within fifty years of the Spaniards' arrival, the Ohlone or Coastanoan culture and way of life had virtually disappeared in the Bay area.Today, two of the Coastanoan tribes, the Awaswa people 'missionized' in Santa Cruz and the Mutsun people 'missionized' at San Juan Bautista, have joined together as the Amah Mutsan Tribal Band in an effort to protect and maintain the authentic and distinct cultural history and practices.The first European land exploration of Alta California, the Spanish Portolá expedition led by Gaspar de Portolá, passed through the area on its way north, still searching for the "port of Monterey" described by Sebastian Vizcaino in 1602.
