Parth Galen
There were three peaks at the south end of the lake, Nen Hithoel, of which Amon Hen was the westernmost, Amon Lhaw the easternmost and the island Tol Brandir the central one. The travellers passed to the west of it and landed by a little stream in the lawn of Parth Galen. (The Breaking of the Fellowship; Bk 1).
When Frodo sat on the top of Amon Hen (The Mount of Seeing) and put on the Ring, he could see a vast circle reaching from Isengard to Barad-dur and from the Misty Mountains down to the delta of the Anduin – a radius of a good 300 miles.
The map shows the route by which Frodo and Sam left the others, the course of Boromir’s funeral boat, and the various ways taken by the companions when the Orcs seized Merry and Pippin. (The Breaking of the Fellowship; Bk 1).
