Oil in pre-Columbian California

Native Americans were keenly aware of oil reserves in California, and they relied on its utility for thousands of years, albeit not for energy sources. The most abundant oil seep in the ancient California territory was the La Brea Tar Pits, in present-day Los Angeles. Native Americans used oil from La Brea and other seeps primarily as a lubricant, but they also used it as a sealant to waterproof canoes. When Spanish explorers arrived in California in the 1500s, they also used oil to seal cracks in their ships and the roofs of their homes.
