The Yokuts Indians were the first people to settle in the San Joaquin Valley, roughly 8,000 years ago. In 1776, the Spanish missionary Father Francisco Garcés became the first European to explore the area. In 1851, gold was discovered in the Kern River in the southern Sierra Nevada mountains, and in 1865, oil was discovered in the valley. The Bakersfield area, a tule- reed-infested malarial swamp, was first known as Kern Island to the handful of pioneers who built log cabins there in 1860. The area was subject to flooding from the Kern River delta, which occupied what is now the downtown area.
