Name that cactus…

Can anyone (without looking it up on the internet) tell me what variation of cactus this is? I have never seen any like this before.

The green part looks like a branch on a Christmas tree. I have a name in mind but want to wait until I get to my destination to see if I’m right.

There are times I feel like I could tie my steering wheel to something to keep me going straight and take a short nap…

You can’t tell from the smaller pictures in the post, but if you save them to your computer and look at them full-screen you’ll find that in both pictures you can see the road going even further straight, off into the distance, which I what I could see with my own eyes and is why I took the photos.
