Coalinga, California, was founded in 1888 as &#8220;Coaling Station A&#8221; for the Southern Pacific railroad. Its history is founded upon the oil derricks depicted on the patch of its police department. Since the late-19th century, the city has played a key role in California&#8217;s oil production. Coalinga is located near California&#8217;s South Coast Ranges, also depicted on the city&#8217;s police patch.
