Imagine two places exist, both called The Haunted Forest. How would I specify which forest is being referred? Would one say the northernmost Haunted Forest, or the northernmost The Haunted Forest?
If the is dropped, what is the rule that makes it appropriate to do so, and would it be any different if instead of a place, I referred to, for example, a book title?

The simple answer is that generally you don't use the definite article twice. It's just awkward. One the is enough to define what you're talking about.
If one is referring to the Ashdown Forest*, you don't use "the English The Ashdown Forest" to contrast it with another. It's "the English Ashdown Forest".
Similarly with book titles. The Homecoming is a title of a book by Harold Pinter. It's also a book by Ray Bradbury. But again, it's not "The The Homecoming by Pinter is longer than Bradbury's," it's "The Homecoming by Pinter is longer." Typographical conventions help with book titles of course.
*It's quite surprising how many references to "Ashdown Forest" it's possible to find. But one is always "on the Ashdown Forest," not "in Ashdown Forest."
