So I have this cave that is quite large, it is 8 cells long, and objects on the opposite side are vanishing unless the player runs to the other side, making them load. What are recommended solutions to this problem other than shrinking the cave?

Is there some way to put fog in the cell so that the player can't see the entire cave at once? Are there some recommended overhead objects to obscure the view of objects that haven't loaded yet? (I know some people are bugged by having their distant vision in game obscured, but anything is better than the... Skybox (I think that's the right term) showing up when it isn't supposed to.
