"Annie Oakley" TV series (1956)
Here's a scene starring the always fascinating Wrench Rock — sometimes called Indian Head, Upper Indian Head or Bobby — in a relatively artistic shot from the TV show "Annie Oakley." This scene appears in the 1956 episode "Dilemma at Diablo." I love the full reflection of the rock in the pool of water.
Also visible in the shot are the Aztec and the background hill Two-Humper, an important Iverson marker. The main features seen here are located on the South Rim of the former Upper Iverson Movie Ranch in Chatsworth, Calif.
The same setting in recent times
Here's the same group — Wrench Rock, the Aztec and Two-Humper — in a recent photo taken from close to the same angle. The shot is taken in springtime when California's neon green is in full bloom.
Wrench Rock was apparently originally called "Indian Head" until that name became associated by mistake with another rock, which was originally known as Tower Rock (and sometimes called the Pinnacle), located on the Lower Iverson.

Tower Rock, often called Indian Head (and often seen paired with another big rock, properly known as Sphinx but often called Eagle Beak), became one of Iverson's most famous rocks, helped by an appearance in John Ford's 1939 epic "Stagecoach."
My guess is that's one reason Wrench Rock ultimately started being called other things, including Upper Indian Head, which isn't exactly elegant. (But then, neither is Wrench Rock.)

I didn't help matters when I came along years later, unaware of any of the rock's existing names, and started calling it Bobby. But I've since come to my senses, and I think Wrench Rock is the least confusing name for it.
