I nearly backed into this cactus when I was taking a photo - and not paying attention. From what I can work out, it is a Golden Cholla aka Silver Cholla aka Wiggins Cholla aka Cactus Sharpus
...and I believe *all* cholla are "jumping cholla"! NEVER tangle with them! I one had a piece of (such a cute name...) "Teddy Bear Cholla" go through my canvas tennis shoe and lodge in my foot. Didn't have a way to pull it off my shoe and couldn't take off my shoe because it was stuck into my foot! One doesn't forget times like that...I was in my teens!
