Beleriand Geography

South of Ard-Galen the great highlands named Dorthonion stretched for sixty leagues from east to west...
-Pg. 141 Ballantine Edition

Now, a league is 7 miles correct? That means that Dorthonion streched for 420 miles east to west. So, by the take-a-ruler-and-estimate rule, Beleriand (from west at Vinyamar to east and Ered Luin behind Lake Helevorn) is almost 4000 miles across. That is truly amazing especially to look at the huge mass of land in the map in LoTR compared to what is in The Silmarillion. So, all the walking and stuff these people did, really took them a while to do. And imagine what distances Frodo and Sam in LoTR had to cover!

Just another rant.
