Peak shape

I can't believe I forgot to mention Arizona's claim to "fame" in the Civil War!

The Battle of Picacho Peak (or Pass) was an engagement of the American Civil War on April 15, 1862. The action occurred all around Picacho Peak, 50 miles northwest of Tucson, Ariz. It was fought between a Union cavalry patrol from California and a party of Confederate pickets from Tucson, and marked the westernmost battle of the American Civil War.
