View of Signal Hill oil fields, ca.1930

Photograph of a view of Signal Hill oil fields, ca.1930. Hundreds of tall wooden oil derricks are visible on an oil field that stretches from the foreground into the distance. The derricks are tapered airy structures with a platform halfway up and another platform at the top. A crude wooden building can be seen at the base of a derrick at center, while a long wooden building can be seen at the bottom of a small hill at right. Steam is spewing from a structure at right
