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 a 1956 episode called "Dilemma at Diablo." I love the full reflection of the rock in the pool of water.
Also visible in the shot are the Aztec on the left (next to the horse, if you can make it out) and Two-Humper, an important Iverson marker, in the top left corner. (See detail shots below.)

Here's the same group — Wrench Rock, the Aztec and Two-Humper — in a recent photo taken from more or less the same spot. The shot is taken in springtime when the California neon green is in full bloom.
Wrench Rock was probably the original "Indian Head" that became confused with another rock, located on the Lower Iverson, originally known as Tower Rock. Tower Rock, later known as Indian Head (and often seen paired with another rock, known as Eagle Beak or Sphinx), became one of Iverson's most famous rocks, helped by an appearance in John Ford's epic Stagecoach. That's why 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.
If you want to get deeper into the complexity of rock names at Iverson, here's a blog post tackling the movie ranch's various Indian Heads.
