[Mithadan]

Let's start with the LoTR map. On the far left, just west of the Shire is a mountain range called Ered Luin (Blue Mountains). It is split by the Gulf of Lune. To the west of the mountains are Forlindon and Harlindon. The Ered Luin is the same mountain range as appears on the far right (east) of the map of Beleriand found in the Silmarillion. Lindon is the last remnant of Beleriand (primarily Ossiriand) which exists during the Third Age almost 7000 years later. The Sil. tells how the lands changed.

Aman was a large land mass west of Beleriand and Middle Earth. To get there you must cross the ocean or the Helcaraxe (the Grinding Ice) of the far north.
