Signal Hill changed forever when oil was discovered. The hill would soon become part of the Long Beach Oil Field, one of the most productive oil fields in the world. On June 23, 1921, Shell Oil Company's Alamitos #1 well erupted. The gas pressure was so great the gusher rose 114 ft (35m) in the air. Soon Signal Hill was covered with over 100 oil derricks, and because of its prickly appearance at a distance became known as "Porcupine Hill". Today, many of the oil wells and pumpjacks are gone, although quite a few still remain. Signal Hill is now a mix of residential and commercial areas.
