High Pass
The High Pass or Cirith Forn en Andrath in Sindarin[1] was a pass over the Misty Mountains.
On its western end is the refuge of Rivendell, and from there the Great East Road climbs into the mountains until it reaches the mountain under which lies the Goblin-town.
The High Pass was first created during the First Age by Oromë the Vala, in order to allow for a crossing of the mountains by the Eldar. Later the High Pass was used by the Dwarves, who connected their roads (the Great East Road and the Men-i-Naugrim through Mirkwood) with it.[source?]
It's worth noting that there are actually two passes at this location. The lower pass is more prone to being blocked by Orcs, hence most travellers using the higher pass outside of those rare occasions when the Orcs were suppressed.
In the Second Age the High Pass was used by the army of Gil-galad and Elendil when they marched to Mordor in the War of the Last Alliance of Elves and Men. After this war Isildur was slain by Orcs watching the way towards the pass.
During the later Third Age, the Pass became dangerous again because of the Orcs, only with the War of the Dwarves and Orcs, which nearly wiped out all Orcs of the mountains, did it became safe again. Nevertheless in Third Age 2940, the goblins of Goblin Town had burrowed their way back to it, and Bilbo Baggins and the Dwarves of Thorin Oakenshield were captured the next year during the Quest of Erebor.[2]
During the War of the Ring, Grimbeorn kept the High Pass open[3] but the Fellowship of the Ring bypassed the High Pass because the eastern side of the Misty Mountains had become too dangerous.
