Is the water slide at AK an open or enclosed tube?

I don't like the one at the Poly because it is all enclosed and makes me claustrophobic. I'm hoping the tube on the AKL one is open.

I've never been down it, however, it's not a very big slide at all, and I think a small portion of it may be enclosed, but not all.
If you look to the very far right if this photo, you will see the slide -- the white thing:

**Edited to add the people on the resorts board will probably be more helpful!

I don't remember any of the AK slide being enclosed--thought it was kind of wimpy.
