Pico Canyon oil works at the back of Pico Canyon, the valley between the PCO and CSO hills.
According to local oil historian Stan Walker, the view is to the south. "The first derrick in the foreground is Pico No. 5,
then further up the creek is Pico No. 4 (with the pinched-in derrick top). The machine shop is just past No. 4, and then Pico No. 1
is in the distance at left. PCO Hill is on the left and CSO Hill is on the right."
Back of photograph in SMU collection reads: [handwritten] First wells in California, Pico Oil Works where oil [sic] at Pico Canyon Newhall 1885.
