Question: where are tar pits found in the us?
Answer: La Brea Tar Pits, tar (Spanish brea) pits, in Hancock Park (Rancho La Brea), Los Angeles, California, U.S. The area was the site of “pitch springs” oozing crude oil that was used by local Indians for waterproofing. Gaspar de Portolá's expedition in 1769 explored the area, which encompasses about 20 acres (8 hectares).
