The Others made it. When they had Kate and Sawyer captive they were making them clear rocks off it.
Wasn’t that what the Others were building?
Frodo!! 
Oh, duh. Yeah, of course.
They cleared that distance in RotK Denethor record time!
Ooh! I’m a bit dizzy! I didn’t even realize I was holding my breath until they cleared the trees!
Jack is the new smoke monster, then?
Nah. Just another skeleton down there.
That being said, someone should leave a note. Don’t pull the plug.
No, he will be the new smokey - but unlike MIB, he volunteered for it…
It threw the Man in Blacks body out when he became Smokey. Whose Skeleton is that then?
There were a few. Add that to the list of questions.
Maybe Mother’s? I think she was a smoke monster too.
“Hallelujah! Praise Destructo-God!”
They’re going to church?
Jacob layed MIB body with Mother after MIB killed mother in the cave from the first season.
Oh, Hurley! Only you would know exactly the right thing to say to heal Ben…
That was her new body, like FLocke’s at the bottom of the cliff.
Funeral…
Which they just said.
I don’t think it’s that easy.
I suddenly don’t like where this is heading…JACK?!
